Description:A519 Grade AISI 4140 Alloy Steel Seamless PipesTempering A519 4140 Alloy Steel Seamless Pipe and Tubes AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature.Grade AISI 4140, 4130 Steel AISI 4130 1.7218 25CrMo4 SCM430 The actual tempering temperature will be chosen to meet the required properties.Heat the AISI 4130 carefully to a suitable temperature,usually between 400-570, soak at the temperature for 2 hours per 25mm of ruling section, then cool in air.The lower the tempering temperature

AISI 4140 Alloy Steel 1.7225 SCM440 42CrMo4

AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F). AISI 4140 MODIFIED Quenched & Tempered Bar - Chromium AISI 4140 modified is a low alloy hardened and tempered steel suitable for the manufacture of oil and gas downhole tools used in production and completion processes. General Engineering applications include construction components exposed to heavy strain, such as shafts, gear, bolts etc. AISI 4140 can also be used in hardened condition as machine parts exposed to heavy wear. Fabricating and Repairing 4130 and 4140 Steels in Heavy Welds that are to be quench and tempered after welding require the use of a 4130 or 4140 filler metal, as most low-alloy filler metals of sufficient tensile strength lack the carbon required to respond appropriately following a quench and temper option. Apply preheat. The higher hardenability of 4130 and 4140 steels increases the ease at which a hard, brittle microstructure in the heat-affected zone or
