AISI 431/JIS SUS431 1.057 martensitic heat resistant stainless steel bar
Production
431 belongs to martensitic stainless steel, commonly known as stainless steel iron 304 belongs to austenitic stainless steel 431 relative to 304, high strength, poor corrosion resistance, the price is lower than 304. 2 kinds of materials have their own advantages, mainly look at the use and cost of choice materials. If you want to corrosion resistance and high strength, then you can now 2205 duplex stainless steel, the price is much higher than 304.
