17-4 PH ROUND BARS

PH stainless steels are a types of alloys which are resistant to the effects of corrosion.17-4 PH stainless steel is a martensitic, chromium-nickel-copper precipitation-hardening stainless steel.One of the most widely used types of PH stainless steel is 17-4 PH stainless steel. 17-4 PH stainless steel have good resistance to stress corrosion cracking in the lower strength conditions also.17-4 PH stainless steel used in various application including Aerospace applications, Chemical processing equipment, Food grade stainless steel for processing equipment, general metalworking applications that call for precipitation-hardening stainless steel etc. its also known asType 630. It contains approximately 3–5% (4) nickel and 15–17.5% (17) chromium as well as 3–5% copper.its used for applications where high strength and a moderate level of corrosion resistance is required.17-4 PH High strength is keep to approximately 600°F (316°C). AE type 630 stainless steel more commonly known as 17-4 as well as  UNS 17400. 17-4 PH stainless steel grade should not be used at above 572°F (300°C) temperatures or at very low temperatures.17-4 PH is best Stainless which offers high quality standards including AMS 5643, UNS S17400, ASTM A693 Grade 630 and ASTM A564.
