17-7 PH stainless steel pipe in China
The corrosion resistance of 17-7PH is better than that of common martensite stainless steel. Jawaysteel Co.,Ltd specializes in 17-7ph materials. Such as 17-7 PH Stainless Steel Pipe.
17-7 PH, which has another name of Grade 631, is precipitation hardening stainless steel with good performance on form-ability. 17-7PH is a kind of unstable austenite stainless steel after solution treatment which is with toughness and good processability. Generally speaking, 17-7 PH Stainless Steel Pipe is made up by sheet.
Chemical composition of 17-7PH annealed stainless steel sheet:
C: ≤0.09
Mn: ≤ 1
Si: ≤1
Cr: 16.0~18.0
P: ≤0.04
Al: 0.75~1.5
Ni: 6.5~7.75
S: ≤ 0.035
It’s chromium-nickel-aluminum stainless steel used in up to 800F and detailed and intricate parts since low distortion after quenching and tempering.
