Product Description

sncm439 tg&p bright steel round bar

sncm439 steel is one kind of nickel chromium molybdenum high alloy special steel in JIS standard known for it's toughness and ability to attach high strength and hardness after heat treatment. sncm439 steel equivalent material are 40CrNiMoA in GB standard, aisi 4340, sae 4340, astm 4340 in American standard and 34CrNiMo6 in DIN standard. Aster quenching and tempering, sncm439 steel bar will get high tensile strength, high yield strength, high hardness and toughness, so sncm439 steel bar is usually used to produce high strength tie rods, bolts, screws, nuts, gears, shafts, pistons and other automotive components etc. As a steel bar factory, we can supply both raw material of sncm439 hot rolled steel round bar and further processing delivery condition sncm439 steel bars such as sncm439 cold drawn steel round bar, sncm439 peeled steel round bar, sncm439 turned steel round bar, sncm439 centerless ground and polished steel round bar, sncm439 heat treated steel bars such as sncm439 annealed steel round bar, sncm439 normalized steel bar, sncm439 quenched and tempered steel bar ( sncm439 qt steel round bar, sncm439 q&t steel round bar). 

sncm439 turned, ground and polished precision shafting is produce by sncm439 cold drawn or hot roll steel bar to get precision dimension and better straightness in the production of shafts. The straightness is quite important to shafting CNC machining. sncm439 TG&P is used to produce crankshafts, high-speed motor shafts, axle shafts, pup shafts, etc.

sncm439 ground and polished steel bar we supply includes following advantages:

Consistent mechanical properties

Deep mechanical properties (from surface to the center according to your requirement)

Even hardness on the whole bars/Tougher and Increased strength

No brittle, UT testing/Precision size tolerance/Good straightness

Good Roughness/Professional technical service/Competitive price/Fast delivery
