Stainless Steel Rod 630

We are a reputed name in this industry as a Exporter & Supplier of Stainless Steel Rod 630 in Wuxi, Jiangsu, China.
17-4PH alloy is a precipitation of copper, niobium / columbium constituted hardening martensitic stainless steel. This level has high strength and anti-corrosion properties. After heat treatment, the mechanical properties of the product more perfect, can reach up to 1100-1300 mpa (160-190 ksi) of compressive strength. This level can not be used above 300A C (572A F) or under very low temperatures, its atmosphere and dilute acid or salt has good corrosion resistance.

17-4 Precipitation Hardening also known as Type 630 is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius).
17-4 PH alloy can be welded the following:. SMAW, GTAW, PAW and GMAW preliminary test (to check for cracks and weld metal toughness), the SAW welding can be carried out. Because ferrite solidification, reduces the likelihood of weld metal hot cracking and thermal deterioration. In general, does not require preheating, intermediate temperature should be controlled at 120 A C (248 A F).
