Martensitic precipitation-hardening stainless steel provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties at temperatures up to 316°C, good toughness in both base metal and welds, and short-time, low-temperature heat treatments that minimize warpage and scaling.
|17-4PH||Alloy 17-4ph has an ideal combination of corrosion resistance, good mechanical properties at high temperatures and high yield strength which result it to suitable alloy for many applications.||Alloy 17-4PH can be machined in solution treated as well hardened conditions. Machining characteristics depends and vary according to the hardness of the metal achieved after heat treatment. High speed tools and carbide tools are preferred.||17-4 PH Stainless Steel provides excellent weldability propery and can be readily wieldable by arc welding process , with air cooling gives good property.||17-4 PH Stainless Steel provides excellent corrosion resistance. It withstands corrosive attack better than any of the standard hardenable stainless steels|
