What is chemical composition of OHNS steels?

Answer 1

oil hardened non shrinking stell

carbon0.9-1.3%

cromium 0.5%

tungsten 0.4-0.8%

its an alloy steel mainly used for forming dies,its hardened upto 50to 55 hrc

Answer 2

OHNS (Oil Hardening Non Shrinking) steel typically contains a composition of around 0.85-1.00% carbon, 1.30-1.60% manganese, 0.15-0.35% silicon, 0.40-0.60% chromium, and 0.90-1.20% vanadium. It also has trace amounts of phosphorus and sulfur.

Answer 3

Oil Hardened Non-shrinking Steel / Oil Hardened Nickel Steel (Same Say)

C: 0.95, Mn: 1.15, Cr :0.5, W:0.5, V:0.2

Answer 4

Example: iron; 0,90-1,10 % carbon; 0,90-1,60 % manganese; 0,40-0,60 % chromium, 0,40-0,60 % wolfram.

Answer 5

hardness of the ohns is 60-70 hrc

Answer 6

180-220 bhn
