GARBA 177 Supreme® is a semi-austenitic precipitation-hardenable stainless steel, processed by ESR (Electro Slag Refining), which reduces the risk of harmful inclusions. The ESR process together with a shaved surface improves the fatigue resistance as compared to GARBA 177PH.
for applications with very high cyclic fatigue requirements
Remelted steel with excellent inclusion cleanliness and structure. Precipitation hardening for increased strength.
suitable for use in slightly elevated temperatures
