The Alloy Steel JIS G4105 SCM415 Pipes made by Amardeep Steel Centre are some of the best in the world. Items like cylinder pistons, crankshafts, gears, pins, shafts, and so on that need to be tough or wear-resistant are made out of SCM415 that has been carburized on the surface.
SCM415 Steel is a high-quality alloy structural steel that has been quenched and tempered. It is an oil-quenched and tempered steel with a hardness of 28-34 HRc and a medium carbon content. The hardness of SCM415 after annealing is less than 250HB.
SCM415 steel pipes can be hardened more and are not brittle when they are hot. It is unlikely that cold cracks will form, but the ability to be machined and the ability to be stretched when cold are both good.
SCM415 alloy steel is very easy to weld. lloy Steel JIS G4105 SCM415 seamless pipes in the condition of conditioning or carburizing and quenching are used to make high-pressure pipes and all kinds of fasteners, like gears, more senior carburized parts, shafts, and so on. These pipes are used in corrosive mediums and at temperatures below 250°C. JIS 4105 seamless pipe in the condition of conditioning or carburizing and quenching is used to make corrosive mediums that can be used at temperatures below 250 degrees Celsius. In the oil and gas industries, JIS G4105 steel pipe is used a lot.
JIS G4105 is a Japanese Industrial Standard that describes chromium-molybdenum steel, which is mostly used to build the structures of machines. Hot forming methods, such as forging and hot rolling, are used to make JIS G4105 SCM415 pipes. These pipes are often used after more forging, cutting, and heat treatment. This JIS G4105 alloy is better at getting hard and doesn't get brittle when it gets hot. Alloy Steel JIS G4105 SCM415 is easy to weld and has a low tendency to crack when it gets cold. It also has a high mability and cold plastic strain. JIS G4105 SCM 420 has good resistance to fatigue, impact, static strength, and the ability to get harder without getting too hot. But JIS G4105 pipe is hard to weld, so it needs to be heated to between 150 and 410 °C before welding. JIS G4105 SCM415 is used after it has been quenched and tempered at a high temperature. For many years, Tubos has been selling JIS G4105 SCM415 structural steel pipes. We have JIS G4105 Steel Pipes for sale at a low price. Please look over the JIS G4105 steel grades below.

SCM415 Alloy Steel Applications
It is used to build things like high-tensile shafts, bolts, nuts, gears, pinions, and spindles. Locomotive traction with the big gear, supercharger drive gear, pressure vessel, rear axle, gear load of connecting rod, and a spring clip. SCM415 can also be used to under 2000 m deep well of oil drill pipe joint and fishing Alloy, and can be used for bending machine mould, etc.
