Product Description

BÖHLER Grade A750 is an austentic, corrosion and heat-resistant chromium nickel steel, niobium stabilized and solution treated. It have been used typically for parts requiring good corrasion resistance and which will be subjected to elevated temperatures during fabrication or in service and for parts requiring oxidation resistance up to 1500 °F (816°C),
but usage is not limited to such applications. Compared to common 13% chromium steel, it offers higher corrosion resistance at lower strength and good weldability. No post-weld heat treatment required. The steel is resistant to atmospheric corrosion and the action of steam, water and acid as well as alkaline solutions. For optimum resistance, surfaces should be pickled or polished. Cold forming properties are very good. The steel is capable of taking a mirror finish.

Melting Route
