17-4PH , 15-5PH , 17-7PH Stainless Steel Bar Precipitation-Hardening Stainless Steel
Precipitation-hardening stainless steel is in stainless steel stainless steel by single or compound
hardening elements, for high strength, high toughness, high
corrosion resistance, oxidation resistance and excellent
formability, weldability and other comprehensive performance. High
strength alloy material, and with special technology processing.
Guangda through a special process to optimize the service life of the stainless steel valve box products up to 500 hours has wear-resisting, corrosion resistance, impact resistant material, greatly prolong the service life of the product, improve the stability of the product.
