Ferritic Steel TP405 is a low carbon, 12% chrome steel, not subject to appreciable hardening through air cooling from high temperatures. This tendency retards the formation of hardening cracks caused by welding. Practically the same corrosion and oxidation resistance as TP410. Can be machined, drawn, spun and formed without difficulty. Used for applications where hardening upon cooling from high temperatures must be avoided. Has excellent long-time stability up to 1200°F.
| TP405 Grade Characteristic |
| • Basic martensitic stainless |
| • High mechanical properties after heat treatment |
| • Hardenable, Hardness 5HRB higher than common Austenitic Stainless |
| • Corrosion and sealing resistent up to 1200 F (649°C) |
| • Good resistance to hydrogen and hydrogen sulphide |
| • Good weldability by TIG, MIG, MAG and manual electric arc welding, preheat 200-300°C |
| • Machining is performed in the same way as for plain carbon steels of the same tensile strength |
| • Used for heat exchanger in cracking installations in the oil industry |
| • Temperature range between 425°C and 525°C must be avoided owing to embrittlement at 475°C |
