Product Description

Product Description

SUH1 heat-resistant steel, a martensitic heat-resistant steel, has a slightly higher chromium content, which improves its oxidation resistance and thermal strength, and reduces its sensitivity to temper embrittlement. SUH1 heat-resistant steel is used for manufacturing intake valves of internal combustion engines and exhaust valves operating at temperatures below 700 ºC. It can also be used for manufacturing furnace components operating at temperatures below 850 ºC
