ASME SA517Gr.E quenched and tempered steel plates supplier

Gangsteel supplies ASME SA517 Grade E (ASME SA517 GR.E) quenched and tempered alloy steel plate for fusion-welded boilers and other pressure vessels. Grade E is the chromium-molybdenum-titanium-boron grade of the ASME SA517 Steel Plates range, with a minimum yield strength of 100 ksi [690 MPa] in plate 2.50 in. [65 mm] and under, and SA-517 limits Grade E plate to a maximum thickness of 6 in. [150 mm].

All SA-517 grades are heated to not less than 1650 °F [900 °C], quenched in water or oil and tempered at not less than 1150 °F [620 °C], and all grades share the same tensile requirements. Above 2.50 in. [65 mm] the minimum yield drops to 90 ksi [620 MPa], which applies to Grade E up to its 6 in. [150 mm] limit. The grades differ in alloy design and in the maximum thickness each one is allowed. SA-517 Grade E uses high chromium (1.40 – 2.00%) and 0.40 – 0.60% molybdenum, with titanium and boron and no nickel requirement; it has the highest chromium range in the family, and vanadium may replace part or all of the titanium on a one-for-one basis. Grade Q has the same 6 in. [150 mm] limit but is a nickel-chromium-molybdenum-vanadium grade with no boron requirement (SA517 Grade Q). The other grades are Grade A, Grade B, Grade F, Grade H, Grade P, Grade S. Choose the grade named on the drawing or purchase specification; one grade is not automatically a substitute for another.

Note: Most SA-517 limits are ranges, not maxima; only values marked max are maxima. Elements not listed have no requirement for SA517GR.E. P and S maxima apply to both heat and product analysis, and the ASME SA-517 text adds a footnote that also applies the boron limit to both. Older ASTM A517 editions (for example A517/A517M-06) allowed 0.035% P and S; current editions give 0.025%. The actual heat analysis is shown on the mill certificate. Confirm all limits against the SA-517 edition named on your order.

Mechanical Properties

Plate thickness	Tensile Strength ksi [MPa]	Yield Strength min ksi [MPa]	Elongation in 2 in. [50 mm] min %	Reduction of Area min %, rectangular specimen	Reduction of Area min %, round specimen
2.50 in. [65 mm] and under	115 – 135 [795 – 930]	100 [690]	16	35	45
Over 2.50 in. [65 mm] to 6 in. [150 mm] (Grade E maximum)	105 – 135 [725 – 930]	90 [620]	14	–	45

Note: Yield strength may be determined by the 0.2% offset method or the 0.5% extension-under-load method. Plates 3/4 in. [20 mm] and under are tested with the 1½ in. [40 mm] wide rectangular specimen; thicker plates may use the full-thickness rectangular or the ½ in. [12.5 mm] round specimen. Elongation adjustments follow SA-20. Transverse Charpy V-notch specimens must show a lateral expansion opposite the notch of not less than 0.015 in. [0.38 mm]; the test temperature is agreed between purchaser and manufacturer but may not be higher than 32 °F [0 °C]. Guaranteed values for ASME SA517 GR.E must be confirmed on the mill certificate for the ordered thickness and edition.

Note: Heat analysis values; “–” means no requirement. P 0.025 max and S 0.025 max apply to all eight grades. All grades share the same tensile table (100 ksi [690 MPa] min yield and 115 – 135 ksi [795 – 930 MPa] tensile to 2.50 in. [65 mm]; 90 ksi [620 MPa] and 105 – 135 ksi [725 – 930 MPa] above that, where the grade’s thickness limit allows), the same quench-and-temper rule and the same Charpy lateral-expansion requirement. The same strength does not make two grades interchangeable; a change of grade needs the purchaser’s approval.

Available Dimensions

Thickness: up to 6 in. [150 mm], the SA-517 maximum for SA517 Gr.E; exact thickness to enquiry
Width and length: to enquiry
Tolerances: SA-20/SA-20M unless otherwise agreed
Delivery condition: quenched and tempered; plates ordered without this heat treatment are stress relieved by the manufacturer, and the purchaser is then responsible for the quench-and-temper treatment
Supplementary requirements by order: for example S1 vacuum treatment, S2 product analysis, S3 simulated post-weld heat treatment of test coupons, S6 drop weight test, S7 high-temperature tension test, and ultrasonic or magnetic particle examination (S8, S9, S11, S12)

Main Applications

Fusion-welded pressure vessels where the design calls for 100 ksi [690 MPa] class quenched and tempered plate
Fusion-welded boilers within the scope of SA-517
High-pressure storage vessels where higher allowable stress reduces wall thickness and weight
Heavy-wall vessel shells and heads up to the 6 in. [150 mm] SA517GR.E limit
Penstocks and other pressure-containing equipment where the project specification names SA-517 or A517

For ASME Section VIII, Division 1 vessels, designers normally check the Code rules for heat-treated, quenched and tempered ferritic materials (Part UHT) for the Code year that applies to the job.

Equivalent Grades of SA517 Grade E

Standard	Grade	Steel Number	Remarks
ASTM A517/A517M	A517 Grade E	–	Companion ASTM grade. Related, but an ASTM certificate is not automatically SA-517 or ASME Code acceptance, and the reverse is also not automatic
ASTM A514/A514M	A514 Grade E	–	Same-letter structural quenched and tempered plate with a similar alloy design; a structural specification without the pressure vessel scope, so not a substitute
EN 10028-6	P690QL1 / P690QL2	1.8881 / 1.8888	Approximate: European quenched and tempered pressure vessel steels of the 690 MPa class; chemistry, thickness bands and impact rules differ
EN 10025-6	S690QL	1.8928	Approximate: structural quenched and tempered steel of the same strength class; not a pressure vessel specification

Equivalents are for reference only. A grade from another standard, or another SA517 grade, is not a direct substitute for ASME SA517 Grade E unless the designer or the project specification accepts it. Check chemistry, thickness limit, strength, heat treatment, impact testing and the named acceptance standard before approving any alternative.

Frequently Asked Questions (FAQ)

What is ASME SA517 Grade E (ASME SA517 GR.E) steel plate?

ASME SA517 Grade E, also written ASME SA517 GR.E, is a high-strength quenched and tempered alloy steel plate to SA-517/SA-517M for fusion-welded boilers and other pressure vessels. ASME SA517 Grade E uses a chromium-molybdenum-titanium-boron chemistry and has a minimum yield strength of 100 ksi [690 MPa] in plate 2.50 in. [65 mm] and under.

What is the maximum thickness of ASME SA517 Grade E plate?

SA-517 limits ASME SA517 Grade E plate to 6 in. [150 mm]. Between 2.50 in. [65 mm] and 6 in. [150 mm], ASME SA517 GR.E must meet 90 ksi [620 MPa] minimum yield and 105 – 135 ksi [725 – 930 MPa] tensile.

What heat treatment does ASME SA517 Grade E need?

ASME SA517 Grade E plates are heated to not less than 1650 °F [900 °C], quenched in water or oil and tempered at not less than 1150 °F [620 °C]. If ASME SA517 GR.E plates are ordered without this treatment, the manufacturer stress relieves them and the purchaser becomes responsible for the quench-and-temper treatment.

Is impact testing required for ASME SA517 Grade E?

Yes. ASME SA517 Grade E is tested with transverse Charpy V-notch specimens, which must show a lateral expansion of at least 0.015 in. [0.38 mm]. The ASME SA517 GR.E test temperature is agreed on the order but may not be higher than 32 °F [0 °C].

What is the difference between ASME SA517 Grade E and ASME SA517 Grade Q?

ASME SA517 Grade E and ASME SA517 Grade Q have the same tensile requirements. Grade Q has the same 6 in. [150 mm] limit but is a nickel-chromium-molybdenum-vanadium grade with no boron requirement. Choose ASME SA517 GR.E or ASME SA517 GR.Q as named on the drawing; changing between them needs the purchaser’s approval.

Is ASME SA517 Grade E the same as ASTM A517 Grade E?

ASME SA517 Grade E is adopted from ASTM A517 Grade E (the 2023 ASME text is identical with A517/A517M-17 apart from a boron footnote), but the editions on the order must be checked. An A517 Grade E certificate is not by itself SA-517 or ASME Code acceptance for ASME SA517 GR.E; ask for dual certification if both are required.

What information should I give when asking for an ASME SA517 Grade E quotation?

For ASME SA517 Grade E, give the SA-517 edition and any Code year the job requires, SA-517 or SA-517M units, thickness × width × length within the 6 in. [150 mm] limit, quantity, the Charpy test temperature, supplementary requirements and the inspection document you need.
