Performance and Categories of Stainless steel
 
Stainless steel,well known as stainless acid resistant steel are mainly divided into martensitic steel, ferritic steel, austenitic steel, duplex stainless steel,and precipitation-hardening stainless steel based on its organization structure. And Chromium stainless steel,chromium nickel stainless steel,Chromium manganese nitrogen stainless steel according to the chemical components.

Heat Treatment:

Heat treatment is only suitable for specific grades of stainless steel. When heat treating a stainless the hardening temperatures, including rate of heating, cooling and soaking times will vary due to several factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult with the heat treatment provider for whole guidance on heat treatment of stainless steel grades. We are delighted to help to work with you the special heat treatment based on your special requirements.

Main features of Stainless steel pipe:
 
Stainless steel pipe is widely used in the field of conveying the liquid, pipeline of heat exchanger,machining plate,fabricating the products of stainless steel. There are different performance based on different usage. Such as acid-base corrosion resistance, intergranular corrosion resistance,stress corrosion cracking,corrosive pitting,weather-proof corrosivity,thermostability,oxidation resistance.If operating at high temperature,it must have satisfied high temperature long lasting strength,plasticity, creep resistance and even more ageing stability performance.
