20MnCr5 Steel

20MnCr5 steel are low alloyed designing case solidifying steel for parts which require center elasticity of 1000 – 1300 N/mm² and great wearing opposition. It is utilized in boxes, cylinder jolts, axles, camshafts, apparatuses, shafts and other mechanical controlling parts.

We fabricate 20MnCr5 steels normally from sizes 23.5mm to 80mm in round frame. We likewise make 20MnCr5 steel in brilliant shape from 22mm to 63.5mm. Likewise we make 20MnCr5 steel in round cornered square (RCS) type of sizes 55mm, 63mm and 75mm.

We are provider of 20MnCr5 steel to various organizations in Mumbai, Pune (eg Chakan, Bhosari, Ranjangaon, and so on), Aurangabad, Ahmednagar, Rajkot, Thane, Nagpur, Kolhapur, Belgaum, Bangalore, and so forth. All our 20MnCr5 provided is Ultrasound and MPI inspected.

We can likewise give you 16MnCr5 composite steels and 16MnCr5/20MnCr5 double guaranteed steels.
