What are the high speed steel strips and material specifications?
High precision (H) and wide and high thickness accuracy (KH) four kinds of strip steel. According to the material condition, two kinds of strip can be divided into chilled and annealed, the former has higher strength and the latter has good plasticity and toughness.
Cold rolled carbon steel strip is made of high quality carbon structural steel by cold rolling. Because the cold rolled strip can be rolled to a specific heat, the rolling strip is thinner, and has higher dimensional precision and higher strengthCold rolled thin thick hot rolled instead for the same purpose, which can save about 30% steel. According to manufacturing accuracy can be divided into general accuracy (P), width accuracy higher (K), thickness
(1) main usesUsed for stamping machine parts, metal products and manufacturing structural parts, etc..(2) the grade and chemical composition of the materialIn line with GB699 (high-quality carbon structural steel technical conditions), the brand is 15-70# steel provisions.
