ASTM A387 Gr11 CL2N Thawv Steel Phaj, Alloy Steel Phaj
1. Cov lus piav qhia yooj yim:
1) ASTM Standard A387 / A387M-11 Chromium-Molybdenum Alloy Steel Sheets rau Pressure Vessels Chemical Composition
Impact Temperature Delivery Condition Normalized + Tempered / Annealed.
2) Txhua qib excepi Qib 21L 22L thiab 9 muaj nyob rau hauv cov qib tensile srength raws li tau teev tseg hauv cov lus Tensile Requirements.
Qib 21L thiab 22L tsuas yog muaj raws li Chav Kawm 1 Qib 91 tsuas yog muaj raws li Chav Kawm 2 xwb.
specification, tam sim no them los ntawm Specification A1017/A1017M.
3) Qhov siab tshaj plaws ntawm daim hlau tsuas yog txwv los ntawm lub peev xwm ntawm cov khoom sib xyaw kom tau raws li qhov yuav tsum tau ua ntawm cov cuab yeej cuab tam.
