34CrNiMo6 steel bar

DIN 1.6582|34CrNiMo6

DIN1.6582/34CrNiMo6 steel is a heat treatable, low alloy steel,used for a wide range of engineering parts. It is capable of being heat treated to produce a typical tensile strength of 1000 -1200 N/mm² which combined with good ductility and resistance to shock. It also has good hardenability,enabling it to be used for medium tensile strengths in fairly large sections, and attain good wear resistance,good impact proper

AISI 4130 Forged round bar


AISI 4130 is a low alloy steel which contains nominally at least 0.28% Carbon, 0.8% Chromium and 0.15% Molybdenum as strengthening agents. It has good strength ,toughness,fatigue strength,and good atmospheric corrosion resistance.Similar to 4140, it has a lower carbon level which gives 4130 improved weldability, at the expense of through thickness strength.AISI 4130 steel is usually used in the quenched and tempered

AISI 4140 Round bar


AISI 4140 steel is Chrome-Moly High Tensile Steel which has at least 0.8%Cr,0.15%Mo as strengthening alloy elements.The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 steel can be oil hardened to a relatively high level of hardness with a tensile strength of 850 – 1000 MPa.AISI 4140 offers a very good balance of strength,toughness
