5140 steel vs 4130 steel: For the different material comparisons, which one we should choose to use?

5140 steel China suppliers, wholesale, distributors, and stockholder–Dongguan Otai Special Steel Co Ltd. We Otai is a manufacturer and has a large quantity of stock in our warehouse. We supply in Round bar, gauge plate steel, pipe, tube, rod, square, hexagonal, blanks, plate, sheet, precision ground flat bar. Including precision ground bar stock, hollow bar, we provide black surface and black surface alloy steel material.

5140 alloy Steel is a high-quality specific hardenability band alloy structural steel.

And it belongs to the high-quality low carbon, Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardenss is 28-34 HRc. Moreover, AISI 5140 steel Annealing delivery hardenss less than 250HB.

AISI 5140 Alloy structural steel properties is a Nickel chromium molybdenum alloy steel specification. Furthermore, AISI 5140 With a lower carbon content range, so AISI 5140 alloy steel has good weldability.

4130 Steel is a high-quality Quenched and Tempered Alloy Structural steel.

It belongs to the high-quality low carbon, Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 18-22 HRc. Annealing delivery hardenss less than 250HB. With a lower carbon content range, So have good weldability.

Requirements for the manufacture of higher intensity than the 35CrMo steel and tempered forging greater cross-section. Such as large locomotive traction gears, supercharger drive gear, pressure vessels, gear, rear axle, greatly affected by load and spring clip link. It can also be used to 2000m deep oil drill pipe joints and fishing tools and can be used bending machine mold, etc.

Otai provides the grinding, milling, polishing, turning, drilling, and other machining services as your required tolerances and size.

Otai does not act as a material handler. We possess proprietary technology and continuously iterates. We undertake every order to end and solve customer’s problem without any hesitation on responsibility. We are welcome to your kind inquiry.
