Description
Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of 660 stainless steel plate in China. With abundant experience, we warmly welcome you to wholesale customized 660 stainless steel plate from our factory. For price consultation, contact us.
660 stainless steel plate, also known as 15-5PH, is an austenitic-martensitic precipitation hardening stainless steel. It has the excellent properties of ordinary martensitic stainless steel and ordinary austenitic stainless steel. It can achieve high strength performance through quenching and tempering.
In addition, the corrosion resistance of 660 high-strength corrosion-resistant steel plate is better than that of ordinary martensitic stainless steel and close to that of ordinary austenitic stainless steel. It performs well in a variety of acidic and alkaline environments and has excellent corrosion resistance. Its tensile strength can reach more than 860 MPa, its yield strength exceeds 550 MPa, and its ductility is not less than 35%.

FAQ
Q1: What is the difference between 660 stainless steel and 316L stainless steel?
A1: 660 is more than twice as strong as 316L, but its corrosion resistance is slightly inferior (especially in strong acidic environments), so you need to choose according to the working conditions.
Q2: Can 660 stainless steel be used in seawater environments?
A2: It can be used for short-term contact, but for long-term use, it is recommended to choose Hastelloy C-276 or 316L stainless steel.
Q3: How to verify the authenticity of 660 material?
A3: Require the supplier to provide a spectral analysis report (Cr≥14%, Cu≥2.5%), and attach ASTM A693 certification documents.
