Product Description

 

Carbon steel is available as bright drawn key steel in flat and square sections. With medium tensile strength key steel is used widely in general engineering for components such as plain, gibhead, taper and parallel keys. Key steel is produced to the required tolerances as specified in British Standard BS46 and BS4235.Carbon spring steel specifications EN42, CS70, CS80, CS95 and CS100 are available as hardened and tempered spring steel strip, annealed spring steel strip, spring steel plate and spring steel sheet. EN43 spring steel is available in bar and plate. The grades commonly conform to BS970, BS1449, BS EN10083-1, BS EN10083-2, BS EN 10277 and BS EN 10278 standards.X120Mn12 1.3401 is a manganese steel with 1% carbon steel and an 11% to 14% manganese content supplied in plate. Offering excellent work hardening properties high manganese steel can be supplied in full plates or cut to your requirements.1020 belongs to high quality low carbon steel, cold extrusion, carburizing and hardening steel. The low steel strength, toughness, plasticity and weldability are good. Tensile strength of 253-500 mpa, the elongation is 24% or higher.

 

Round bar steel: 10#,20#,belongs to the low carbon steel grades, good plasticity, easy drawing, extrusion, stamping, forging and welding, the 20# most widely used steel of.45# is medium carbon steel, after quenching and tempering, excellent mechanical properties can be obtained, is used as an important axis, above the fasteners.60# belongs to high carbon steel production, spring and wear parts of.20CrMnTi is important for carbon steel, gear and other important.27SiMn high strength steel welding is easy, the need for the very important place is 42CrMo.35CrMo welding, high strength steel, for very important parts, such as engine connecting rod screw, the cylinder head screws. Heavy vehicle tires screw.
