ASTM A128 standard hi high manganese steel castings atana standard specification a ni a, chu chu high manganese steel casting chi hrang hrang siamna atan a tha a, chung zingah chuan gravel breaker atan lining plate, jaw crusher atan jaw plate, hammer crusher atan hammer head, etc. Heng castings te hi a tlangpuiin wear a ngai a, impact a ngai a, industrial field dang hman tur a awm a ngai a ni.
ASTM A128 Standard hian manganese steel casting sang tak takte chemical composition, mechanical property, metallographic organization, hardness leh impact performance te a tarlang a ni. Chumi zingah chuan chemical composition hi high manganese steel casting-a wear resistance leh impact resistance tha tak neih theihna tura thil pawimawh tak pakhat a ni. Standard ang chuan manganese steel casting-a chemical component lian ber berte chu carbon (C), manganese (MN), silicon (SI), phosphorus (P), sulfur (S) leh chromium (CR) te an ni a, manganese awm zat hi 11% leh 14% inkar a ni tlangpui. Chu bakah, standard chuan a casting-a metallographic organization leh crystal size chu test a ngai a, chu chuan wear resistance tha leh impact resistance a neih theih nan a pui a ni.
Mechanical property lamah chuan ASTM A128 standard hian manganese steel casting sang tak tak tan tensile, hardness leh impact test a mamawh a ni. Heng test hmang hian tensile strength, yield strength, elongation, hardness leh impact toughness te performance index te chu an hman chhunga nghawng lian tak leh an incheina an tuar theih nan endik theih a ni.
Chemical composition leh mechanical property bakah hian ASTM A128 standards hian heat treatment process leh surface quality high-manganese steel castings atana thil tulte a tarlang bawk. Heat treatment process hian casting organizational structure leh performance a ti tha thei a, a wear resistance leh impact resistance a ti tha thei bawk. Surface quality atana thil tul hrang hrangte chu a lei chunglam roughness, defects leh oxide layer te a ni a, chu chuan casting hian a hman laiin surface condition tha tak a vawng reng thei a ni.
A tlangpuiin ASTM A128 standard hian high-Manganese steel castings performance leh quality chu strict takin a enkawl a, a enfiah bawk a, chu chuan mining, construction leh industrial field dang danga hman tur mamawh a tlin theih nan a pui a ni. He standard hi zawm a nih chuan, high-manganese steel castings wear resistance tha leh impact resistance tha tak siam theih a ni a, hei hian a kaihhnawih industry siam leh hmanna tur rintlak tak a pe a ni.
