Stainless Steel Grade
Martensitic stainless steel is a stainless steel with chromium as the main alloying element, and has the characteristic of being able to obtain high strength and hardness through heat treatment.
We handle various martensitic stainless steel products and provide optimal materials that meet our customers' diverse requirements.
We can supply in various forms such as plates, bars, pipes, and fittings, and provide services across a wider range of industries with material responsiveness and technical reliability that match your process conditions.
