We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

Welding with MAG could require modern pulse tools, and the usage of particular shielding gases containing Ar, He, and O2/CO2 to facilitate good arc stability and improved fluidity. 253 MA Tig Wire is designed for welding the excessive temperature steel 253 MA.

Used for instance in furnaces, combustion chambers, burners and so forth. Both the steel and the consumable present glorious properties at temperatures C. The composition of the consumable is balanced to make sure crack resistant weld steel. 253 MA tends to give a thick oxide layer throughout welding and sizzling rolling. Black plates and previous weld beads should be carefully brushed or floor previous to welding.

Excellent weldability by all normal fusion methods, utilizing matching filler metals. AS 1554.6 pre-qualifies welding of 253MA with Grade 22.12HT rods or electrodes. Grade 309 fillers can be utilized if lower creep power can be tolerated.

Our stainless production range

• 253 MA maintains its heat resistant properties by advanced management of micro alloy additions.
• Stainless 253 MA is a lean austenitic heat resistant alloy with high energy and outstanding oxidation resistance.
• A extensive number of components requiring high power at elevated temperatures similar to heat exchangers, kilns, stack dampers and oven components are frequent applications for 253 MA.
• The use of uncommon earth metals together with silicon provides superior oxidation resistance up to 2000°F.

In some instances, nevertheless, a differing composition could improve e.g. weldability or structural stability. Gas shielded welding has resulted in one of the best creep properties for welds. To facilitate the usage of Therma 253 MA at the highest temperature range, TIG, plasma, or MAG processes ought to be used.

Mechanical Properties

Sandvik 253 MA may also be utilized in nitrogen-containing atmospheres supplied that the gasoline accommodates sufficient oxygen to type a protective oxide layer. In gasoline shields containing little or no oxygen the resistance of Sandvik 253 MA is inferior to that of Alloy 800H and 25Cr/20Ni steels as illustrated in Fig. Thus, the grade isn’t really helpful to be used in muffle tubes using cracked ammonia gas.

They have one other designated property with grade 2111HTR. 253MA Wire has the nice amount of low nickel composition, which helps in reducing sulphide atmosphere once we evaluate it to grade 310 and excessive-stage nickel alloy. They have the strong inclusion of nitrogen, silicon and cerium which makes metal a good oxide with great stability, excellent resistance, larger temperature strength and rather more for sigma notion phase. Sandvik 253 MA is extra resistant than the higher alloyed 25Cr/20Ni steels to combustion gasoline assaults in cyclic circumstances. It has an equivalent resistance, in comparison with the same grades, in conditions that are just about isothermal.

253MA is a grade combining glorious service properties at excessive temperatures with ease of fabrication. It resists oxidation at temperatures as much as 1150°C and might present superior service to Grade 310 in carbon, nitrogen and sulphur containing atmospheres.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
