431 Stainless Steel Sheet

431 Stainless Steel Sheet Supplier in Chinacorrosion resistance

The 431 stainless steel sheets are martensitic, heat-treatable steel. It has better corrosion resistance than the conventional martensitic stainless grades. Grade 431 has good oxidation resistance and torque strength. Thus, obtaining optimum toughness, wear resistance, and high tensile properties. These qualities make them ideal for uses involving bolts and shafts.

TuoLian 431 ss panel is best for marine settings. It is also resistant to various organic chemicals, petroleum compounds, and a number of acidic situations. You can find grade 431 in different diameters, surface finishes, etc. Contact us now to get a better quotation.

431 Stainless Steel Sheet Technique

Welding Stainless Steel Sheet 431

Due to the potential for cracking, welding grade 431 stainless steel is challenging.

Pre-heating materials between 200 to 300°C prior to welding is advised.

Machining 431 SS Sheet

431 is easily machineable with all operations like turning, drilling, etc

All machining must be done in accordance with tool type, speed, and feeds.

Cold Bending
Cold Bending

Type 431 SS panel is simple to bend, draw, spin, and more.


Hot Bending
Hot Bending

Grade 431 steel is heated to 2100-2200 F for optimal results.

Work materials at no lower than 1650 F (900 C).

Forging SS 431 Sheet

Heat the 431-grade panel uniformly to between 1150° and 1200°C.

Do not soak; instead, start forging right away.

Hardening SS 431 Sheet

Hardening 431 can be done through heating at 980–1065 °C.

It can hold for approximately half an hour and then harden by quenching in air or oil.

Nitriding SS 431 Sheet

Nitriding at 500°C to 550°C, and then air-cooled.

Tempering SS 431 Sheet

Temper for the desired qualities. It can be heated to between 590° and 680°C as needed.

Annealing SS 431 Sheet

Grade 431 can be heated to between 620 and 660°C (1200–1500 F) and then air-cooled.
