Rectangular 253ma Stainless Steel, For Automobile Industry, Thickness (Millimeter): 3mm-a hundred Mm

The highly protective oxide layer makes it potential to use this metal at excessive temperatures in atmospheres containing sulphur and different aggressive compounds. 253 MA options wonderful oxidation resistance at temperatures under 1093 °C, above which, its oxidation resistance will decrease.

RA 253 MA displays equal or superior oxidation resistance to many other alloys tested, together with 309 and 310. At 2000˚F (1093˚C), RA 253 MA reveals excellent oxidation resistance, which is the same as the limit for 310 chrome steel and superior to 309. While brief furnace excursions as much as 2100˚F (1149˚C) can be tolerated, consistent oxidizing temperatures above 2000˚F can rapidly degrade the fabric.

A optimistic impact has also been achieved with small additions of so-referred to as (re)active elements, e.g. yttrium, hafnium, and uncommon earth metals (REM, e.g. Ce and La). These have an effect on the oxide development so that the shaped layer might be thinner, tougher, and extra adherent, and thus extra protective. This is very beneficial in situations with various temperatures. RA 253 MA is a lean austenitic chrome steel that uses cerium and silicon to create a really adhesive oxide, leading to wonderful oxidation resistance.

• Conquest Steel & Alloys is a provider and stockholder of 253MA Stainless Steel is a lean austenitic warmth resistant alloy with excessive power and outstanding oxidation resistance.
• The austenitic structure provides this grade wonderful toughness, even right down to cryogenic temperatures.
• 253MA incorporates a fairly low nickel content, which supplies it some benefit in decreasing sulphide atmospheres when compared to high nickel alloys.
• UNS and 253 MA maintains its heat resistant properties by superior management of micro-alloy additions.
• The inclusion of excessive chromium, silicon, nitrogen and cerium contents offers the metal good oxide stability, high elevated temperature (creep) energy and excellent resistance to sigma section precipitation.

Our stainless production range

The mixture of nitrogen and carbon provide creep-rupture power that is double that of kind 310 and 309 stainless at 1600˚F (871˚C). RA 253 MA® is a flexible alloy that can be utilized in a range of thermal purposes for tools construction. The drive for the development of this alloy was the rapid rise in nickel costs. With low Cr and low Ni, RA 253 MA is a good, low-price alternative to other extra-costly nickel-based mostly supplies. With the appearance of the microalloying control, this alloy is comparably priced with 310 stainless-steel, nevertheless it delivers high strength properties similar to the upper nickel Inconel® 600-series supplies.

Thanks to the relatively excessive chromium content and the addition of silicon and uncommon earth metals, a protecting oxide is definitely shaped on the surface of Sandvik 253 MA materials. 5 shows carburization after 500 h at completely different temperatures, in a combination of about 10% methane and about 90% argon containing 0.5% oxygen. As can be seen, Sandvik 253 MA is much less susceptible to carburization at high temperatures in these conditions than ASTM TP310 and Alloy 800H. Conquest Steel and Alloys is a family run company originally having a speciality in carbon steel, stainless-steel and excessive nickel alloys pipes and plates.

Thermocouple safety tubes (pyrometer safety tubes) in a wide range of excessive-temperature corrosion resistant supplies. The Sandvik program includes supplies suitable for all sorts of shielding gases and environments overlaying working temperatures up to 1200ºC (2190ºF). four show that the resistance of Sandvik 253 MA in such tough circumstances is superior to that of both ASTM TP310 and EN 1.4828 (ASTM TP309). The very good properties of this grade in cyclic circumstances have been achieved by adding uncommon earth metals and silicon.

Main Characteristics Of Sandvik 253 Ma

Typical sizzling tensile strengths of several supplies are proven in Figure 1. Over most of the temperature ranges, it’s corresponding to Alloy 600, superior to 310 stainless and RA 330® however lower than RA 602 CA®. Even though hot tensile power is reported up to 2200˚F (1204˚C), the lack of oxidation resistance at 2000˚F makes its practical use restrict 2000˚F (1093˚C) in oxidizing environments.
