17-4PH SUS 630 Stainless Steel Plate 1-30mm Thickness H1150 HRC40 Hardness

 1: Brief Introduction Of 17-4PH stainless steel
Alloy 17-4 is a chromium-copper precipitation hardening stainless steel that is used for applications requiring high
strength and a moderate level of corrosion resistance. It is one of the most widely used precipitation hardening grades,
as it has high strength hardness up to about 572°F while demonstrating good corrosion resistance in all heat treated
conditions. Alloy 17-4 has adequate resistance to atmospheric corrosion or in diluted acid salts where its corrosion
resistance is equivalent to Alloy 304 or 430. Alloy 17-4 can be heat treated to a variety of temperatures to develop a
wide range of properties. Its mechanical properties can be optimized with heat treatment where very high yield strength
up to 180 ksi can be achieved. Alloy 17-4 should not be used at temperatures above 572°F or at very low temperatures.
Corrosion Resistance:
★Withstands corrosive attacks better than any of the standard hardenable stainless steels.
★Comparable to Alloy 304 in most media.
★Corrosion resistant in some chemical, petroleum, dairy, and food process industries.
★Subject to crevice or pitting attack if exposed to stagnant sea water for any length of time.
Weldability:
★Successfully welded by most common fusion and resistance methods.
★Should not be joined by oxyacetylene welding.
★Generally no pre-heating required.
★Inter-pass temperature must be limited to 248°F.
★Better toughness is obtained in the weld after a complete heat treatment.
Machinability:
★Can be machined in both solution-treated and precipitation-hardening conditions.
★Machining conditions may vary with hardness of material.
★High-speed tools or preferably carbide tools with standard lubrication are normally used.
