431 stainless steel is a metal material, the Maza body stainless steel standard standard AISI, ASTM type, model 431, UNS number S43100

431 Chinese is called matewars stainless steel. CR steel containing NI can obtain high -mechanical properties through heat treatment. The corrosion resistance is better than 410 steel and 430 steel. 431 stainless steel corresponds to China 1CR17NI2, Japan JIS SUS431.

431 stainless steel has high strength, but poor plasticity and welding. The commonly used grades of martensite stainless steel include 1CR13, 3CR13, etc. Due to its high carbon content, it has high strength, hardness and abrasion resistance, but its corrosion resistance is slightly worse. It is used for mechanical properties such as spring, steam turbine blades, hydraulic valve and other parts with higher corrosion resistance requirements. After forging and stamping, annealing is required.

431 Stainless steel characteristics and applications: 431 (16Cr-2I) CR steel containing Ni contains Ni. It can obtain high-mechanical properties through heat treatment. The corrosion resistance is better than 410 steel and 430 steel. 431 stainless steel corresponds to China 1CR17NI2, Japan JIS SUS431. ● 431 Chemical ingredients: Carbon C: ≤0.20

Manga MN: ≤1.00

Silic Si: ≤1.00

Chromium CR: 15.0 ~ 17.0

Nicken Ni: 1.25 ~ 2.50

Phosphorus P: ≤0.04

Sulfur S: ≤0.03

When 431 stainless steel is used for certain management processes, the nickel content of some models of Austenite stainless steel must be slightly higher than the value shown in the table.

The alloy 431 is the most corrosive in the martensite grade. Due to the excellent tensile strength and torque intensity of alloy 431, it is used for structural components exposed in the marine environment, and also used for aircraft fasteners and accessories. 431 stainless steel rod, silk, forged tube
