If you are in search of a grade of austenitic chrome steel that might be optimum for machining, 303 Stainless Steel has the compositional properties that make it the ideal candidate. This steel is especially optimum for extensive machining practices because of the increased stage of sulfur current in its composition.

Its corrosion is superior to 416, one other free-machining grade, but is considerably inferior to other 400 series stainless steels which do not include greater sulfur ranges. In order to acquire optimum corrosion resistance, it is suggested that Alloy 303 be chemically treated to take away sulfides from the ultimate surfaces. The sulphur addition present in 303 stainless steel results in poor weldability. If 303 should be welded the beneficial rods or electrodes are grades 308L and 309 stainless steels.

Metals Resources

Grade 303 is the most readily machinable of all of the austenitic grades of stainless steel. The machinable nature of grade 303 is due to the presence of Sulphur in the steel composition. Whilst the Sulphur improves machining, it additionally causes a lower within the corrosion resistance and a slight reducing of the toughness.


  • Like different austenitic grades, Alloy 303 demonstrates wonderful toughness, though the sulfur does reduce this somewhat as properly.
  • It is the free machining modification of the basic 18% / eight% chrome steel.
  • A non-magnetic, austenitic stainless-steel that is not hardenable by heat therapy, 303 stainless-steel plate provides good weather resistance, toughness and forming properties.
  • Alloy 303 is a non-magnetic, austenitic stainless steel that’s not hardenable by heat remedy.

Our stainless production range

It produces small brittle chips and may be machined at excessive speeds with deep cuts and heavy feeds. The cold formability of Alloy 303 is adversely impacted by the excessive sulfur content. The alloy could also be bent with a generous bend radius, nevertheless, when cold forming is required, 304 ought to be utilized. Hardening – Alloy 303 can’t be hardened by therapy, it could possibly only be hardened by cold .

It also has good oxidation resistance in steady service to 870°C. This nevertheless, just isn’t really helpful as 303 is sensitive to carbide precipitation with continuous use at °C. We have the biggest austenitic 303 stainless steel stock in Southern California and supply non-standard thicknesses that no one else in the nation can match. ASTM specs, color codes, stainless grades, and other useful product assets and downloads. Information given in this knowledge sheet in regards to the condition or usability of materials respectively merchandise are not any warranty for their properties, however act as an outline.

Fabrication methods like forging, that involve hot working should happen after uniform heating to °C. The fabricated components should then be quickly cooled to ensure maximum corrosion resistance. 303 stainless-steel has good resistance to oxidation when intermittently exposed to temperatures as much as 760°C.

Alloy 303 is a non-magnetic, austenitic stainless steel that’s not hardenable by warmth treatment. It is the free machining modification of the fundamental 18% chromium / 8% nickel stainless-steel. Like other austenitic grades, Alloy 303 demonstrates glorious toughness, although the sulfur does reduce this slightly as properly. Improve efficiency in rugged environments with 303 stainless-steel plate from Dix Metals.
