321 is also known as 18-8, 0Cr18Ni10Ti, 1Cr18Ni9Ti, 06Cr18Ni10Ti.

0Cr18Ni10Ti: C≤0.08 Ni≤9-12 Cr≤17-19
1Cr18Ni9Ti: C≤0.12 Ni≤8-11 Cr≤17-19
The rest of the ingredients are similar. The prices are also similar.
Performance: high carbon content, higher high temperature performance and corrosion resistance, high nickel content, higher high temperature performance and corrosion resistance.

0Cr18Ni11Ti and 1Cr18Ni9Ti are both austenitic stainless steels. The difference between the two is caused by the different contents of chromium (Cr) and nickel (Ni).

0Cr18Ni11Ti——Carbon content is less than or equal to 0.08%, which is austenitic stainless steel.
Tensile strength σb (MN/m2) ≥520
Yield strength σs (MN/m2) ≥206
Elongation δ5 (%) ≥40

1Cr18Ni9Ti——Carbon content is less than or equal to 0.12%, which is austenitic stainless steel.
Tensile strength σb (MN/m2) ≥550
Yield strength σs (MN/m2) ≥200
Elongation δ5 (%) 〉=40,

The main role of chromium and nickel in stainless steel
Chromium (Cr): In structural steel and tool steel, chromium can significantly improve strength, hardness and wear resistance, but at the same time reduce plasticity and toughness. Chromium can also improve the oxidation resistance and corrosion resistance of steel, so it is an important alloying element for stainless steel and heat-resistant steel.
Advantages:
(1) Chromium can improve the strength and hardness of steel.
(2) Chromium can improve the high-temperature mechanical properties of steel.
(3) Make steel have good corrosion resistance and oxidation resistance
(4) Prevent graphitization
(5) Improve hardenability.
Disadvantages:
(1) Chromium significantly increases the brittle transition temperature of steel
(2) Chromium can promote the temper brittleness of steel.

Nickel (Ni): Nickel can improve the strength of steel while maintaining good plasticity and toughness. Nickel has high corrosion resistance to acids and alkalis, and has rust and heat resistance at high temperatures. However, since nickel is a scarce resource, other alloy elements should be used as much as possible to replace nickel-chromium steel.
