ASTM A240 321 is a type 321 stainless steel manufactured according to ASTM A240 standard. This is an alloy-type austenitic stainless steel with the addition of specific alloying elements to improve its corrosion resistance and high temperature resistance.
ASTM A240 321 Stainless Steel Features:
Excellent corrosion resistance: 321 stainless steel shows excellent corrosion resistance due to its special alloy composition, especially in some corrosive media.
Good high temperature resistance: the material can also maintain good stability in high temperature environment, suitable for some high temperature working conditions.
Good processing performance: 321 stainless steel has good plasticity and weldability, which is convenient for various processing operations.
ASTM A240 321 the main chemical composition of stainless steel including carbon (C) 0.08% or less, manganese (Mn) of 2.0% or less, nickel (Ni) 9.0 ~ 12.0%, and silicon (Si) of 1.0% or less, chromium (Cr) 17.0 ~ 19.0%, sulfur (S) of 0.030% or less, phosphorus (P) of 0.035% or less, And titanium (Ti) 5C~0.7%. The specific proportions of these elements together determine the properties of 321 stainless steel.
Due to the excellent properties of ASTM A240 321 stainless steel, it has a wide range of applications in many fields. For example, it can be used to manufacture chemical equipment, petroleum equipment, medical equipment, and building and decorative materials. In addition, due to its high temperature resistance, it is particularly suitable for work in high temperature environments, such as heat treatment equipment, stoves, etc.
