Equivalent Grades GB 20CrMo,JIS SCM420,ASTM 4118,DIN 25CrMo4.SCM420 are alloy steel with high hardenability,temper brittleness,well weldability,less cold cracking tendency,good machinability,and great cold plastic strain.25CrMo4 / DIN 1.7218 Forged/Rolled Alloy Steel Round Bars DIN 25CrMo is a common chromium molybdenum alloy steel.It contains a lower carbon content compared with 42CrMo4.It will be freely machineable in the condition of HRC18-22.DIN 1.7218 has high hardenability without temper brittleness.The weldability of DIN 1.7218 is quite good.
SA-335P92 steel is in SA-335P91 steel of based Shang,appropriate reduced has Mo elements of content,while joined has must volume of w,will material of Mo equivalent (Mo+0.5W) from P91 steel of 1% improve to about 1.5%,the steel also joined has trace of boron,by above alloy of improved Hou,and 9%Cr series of other common steel compared CN104513893A - Heat treatment method of EA4T steel axle The invention provides a heat treatment method of an EA4T steel axle.The heat treatment method comprises the following steps (1) forging EA4T steel to produce axle blanks,and slowing cooling the axle blanks; (2) quenching heating the temperature of a furnace to a temperature of 860 to 880 DEG C,then placing the axle blanks into the furnace,maintaining the temperature for 1.5 to 2.5 hours
China / GB,Low carbon steels,low alloyed : Total Materia.The largest metals properties database available.Besides being is the most comprehensive metal properties database and knowledge source worldwide,with more than 10,000,000 property records for over 350,000 alloys,Total Materia gives you the highest quality and reliability of the Hydrogen sulphide stress corrosion cracking of 2.25Cr-Mo Jul 01,1997 25mocr4e steel equivalent to 25crmo steel#0183;EXPERIMENTAL METHOD Specimen preparation The material employed in the experiment was an A387Gr22 Cr-Mo steel of 13 mm thick.The chemical composition of the steel in weight percent was 2.25Cr,0.93Mo,0.34Si,0.58Mn,0.11C,0.01P,0.01S,and Fe balance.Two covered electrodes (3.2 mm in diameter) used for HM and HG welds,were ER 9016-B3 and ER
The typical heat-resisting rotor steels such as 2.25CrMo,9CrMo and 12CrW steel were experimentally studied in order to understand their materials degradation under high temperature and pressure Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
