SCM420 Steel introduction
SCM420 steel is a low carbon chrome moly steel used to manufacture surface carburised parts used in auto parts, machinery, capital goods, shafts, fastneners, etc which work in non corrosive environments usually below 250C.
It has high quench hardenability. SCM420 has good weldability. We can provide you SCM420 in sizes from 23.5mm to 80mm.
We are supplier of SCM420 steel to a number of companies in Mumbai, Pune (eg Chakan, Bhosari, Ranjangaon, etc), Aurangabad, Ahmednagar, Rajkot, Thane, Nagpur, etc. All our En15Am supplied is Ultrasound and MPI inspected.
