4.3 Measurements and Predictions of Lower Bound

by grade, heat treatment and class according to two specifications; ASTM A958, and ASTM A487 for castings suitable for pressure service according to the ASME Boiler and Pressure Vessel Code (BPVC). For the data analyzed and grouped according to ASTM A487 and the ASME BPVC specification SA487, lower bound allowables for grades and classes 4A, 4B ASTM A487 Grade 4 Class B ASTM A487/A487M - BBN STEEL Physical properties of ASTM A487 Grade 4 Class B ASTM A487/A487M are mainly indicated by modulus of electrical resistance value, thermal conductivity, specific thermal capacity, coefficient of thermal expansion, elasticity, poisson's ratio, density, etc.

ASTM A487 grades include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, CA15, CA15M, CA6NM, the ASTM A487 Grade CA6NM Class B Heat Treated ASTM A487 A487M for Steel Castings made by Steel Foundry ASTM A487 Grade CA6NM Class B Heat Treated ASTM Welding Procedures A410 to A643 - weldrealityASTM A487 other grades :Casting for pressure service :A487-2N :check for pre/post heat req :E7018-A1 or E8018-B2:A487-4N :check for pre/post heat req :Flux cored E4130:A487-6N :check for pre/post heat req :Flux cored E4130:A487-7Q :check for pre/post heat req :Flux cored E4130:A487-8N :check for pre/post heat req :E9018-B3 E90T5 Improving the quality of high alloy CA6NM stainless steel performed on three grades of CA6NM, namely, A487 Class A, A487 Class B and A743 in both as-received and as-cast conditions. A double tempering at 667ºC and 607ºC followed by different cooling techniques after solutionizing and tempering was employed to test the hypothesis. The

Improved corrosion resistance, particularly resistance to sulfide stress corrosion, can be obtained with a lower carbon as in grade CA6NM Class B (ASTM A487). A lower carbon content, as in grade CA6NM Class B, permits heat treating to a lower

"Specification:ASTM A285 - Grade B; ASTM A516 - Grade 65, 70, 75; ASTM A283 (for draft tube liner); and ASTM A36 (for draft tube liner). "Application:These materials are used on all turbine components of plate steel construction. They are low to intermediate strength materials and have cavitation resistance which is typical of carbon steel. 1 VALVE MATERIALS & SERVICE APPLICATIONSASTM A487 Grade CA6NM 12% Ch ro m e Steel Co rro siv e ap p licatio n at tem p eratures b etw een -20ºF (-30ºC) an d + 900ºF (+ 482ºC).
