OEM manufacturer Stellite 12 - Stainless Steel PH15-7MO – Sekonic

Common Trade Names: Ph15-7Mo,15-7MoPH, S15700, 07Cr15Ni7Mo2Al ,W.Nr 1.4532

15-7M0Ph steel alloy can withstand all kinds of cold forming and welding process under the condition of austenite.Then through heat treatment can obtain 

the highest strength; Under 550 ℃ with excellent high temperature strength,was designed to have greater toughness than 17-4 PH. The  alloy is martensitic in structure in the annealed condition and is further strengthened by a relatively low temperature heat treatment which precipitates a copper containing phase in the alloy.

Why Steel Steel 15-7Mo?

• Can withstand all kinds of cold forming and welding process under the condition of austenite.then through heat treatment can obtain the highest
  strength ,Under 550 ℃ with excellent high temperature strength.

• Electric welding property：The steel can adopt arc welding, resistance welding and gas shielded arc welding, gas shielded welding is the best.
     Welding is often done in materials solid solution treatment conditions,and do not need to preheat before welding.
     When welding requires high strength, the 17-7 with lower content of δ- ferrite is chosen mostly,austenitic stainless steel welding wire can be used

Steel 15-7Mo Application field：

Applied to make aviation thin-wall structure components, all kinds of containers, pipes, spring, valve film, ship shaft,
compressor plate, reactor components,  as well as a variety of structure components of chemical equipment, etc.
