| description abstract | This specification covers 12 percent chromium steel castings for high temperatures and for impact at low temperatures. Castings shall be furnished in the following grades and classes as specified (see 6.2). Grades and classes are identified in ASTM A 217, A 487, or A 757, as appropriate (see 6.2). Grade CA-15 - 12 Chromium (ASTM A 217) CA-15M, Class A - 12 Chromium modified molybdenum (ASTM A 487) E3N - 12 Chromium × 4 Nickel (ASTM A 757) Intended Use: These materials are intended for use in pump casings, compressor housings, gas turbine engines and other applications requiring 12 percent chromium, corrosion resisting steel castings. Grade CA-15 and CA-15M are intended for use in load carrying applications for elevated temperature service. The maximum operational temperature should not exceed 100°F below the minimum tempering or post weld heat treatment temperatures. For maximum corrosion resistance, alloys should be final tempered between 1100°F and 1200°F. Grade E3N castings are intended for use where either CA-15 or CA-15M is used. Grade E3N has better weldability, corrosion and erosion resistance, and improved soundness and casting characteristics over CA-15 and CA-15M. Low temperature properties; that is, notch toughness, are superior for grade E3N. | |
