CA6NM Round Bars, UNS J91540, ASTM A352, A487, A743

Description

CA6NM Round Bars / UNS J91540 Round Bars

CA6NM Round Bars is a Martensitic Stainless Steel product known for its combination of High Strength, Good Corrosion Resistance, Toughness and Suitability for demanding industrial applications. CA6NM is a Chromium-Nickel-Molybdenum Stainless Steel Grade identified by UNS J91540.

CA6NM is particularly associated with applications involving pumps, valves, power-generation equipment, turbines, marine equipment and petroleum-related industries.

CA6NM is one type 12 Chromium 4 Nickel stainless steel Casting grade which listed in ASTM A743, ASTM A352 and ASTM A487 standard. UNS code is J91540. ASTM A757 Grade E3N is same as CA6NM. It’s one “400” series Martensitic Chromium Nickel stainless steel with general high strength corrosion resistant. 

Textron Steel and Alloys supplies CA6NM Round Bars in different sizes and finishes according to customer requirements, with material documentation and testing available as required.
