Note:
1.NAME:carbon constructional quality steel
2.Grades:20#
3.STD:GB/T699-1988
4.Characteristics AND applicant fiend:
Strength is slightly higher than Gr.15, few quenching ,no temper brittleness. With quality Cold deformation plasticity, generally usded for bending, rolling, bending and hammer processing etc. The performance of electric welding arch processing and contact welding is good, the thickness with gas welding is of small, shape is must be in strict or when use for parts with complex shape that is easily happening crack. when Cutting machining lengba, normalization is better than annealing and generally used to manufacture parts with high toughness and less stress.
