Abstract

The invention discloses steel for saw blades. The steel comprises the following chemical components in percentage by mass: 0.69-0.75% of C, 0.30-0.60% of Si, 1.10-1.40% of Mn, less than or equal to 0.15% of Cr, less than or equal to 0.10% of Ni, less than or equal to 0.15% of Cu, less than or equal to 0.08% of Mo, less than or equal to 0.04% of Sn, less than or equal to 0.02% of Sb, less than or equal to 0.025% of Ti, less than or equal to 0.040% of P, less than or equal to 0.040% of S, and the balance of Fe. The invention also discloses a production method of the steel for the saw blades. The steel for saw blades is reasonable in composition control to ensure the compression ratio of steel products, is good in performance, and does not have crackles on the surface. The production method of the steel for saw blades is simple, and a specific smelting process and narrow composition control of carbon are adopted to produce the steel for saw blades, which meets a requirement on narrow composition control during subsequent steel rolling heat treatment.

Description

technical field

[0001] The invention relates to the field of metal materials, in particular to a steel for saw blades and a production method thereof. Background technique

[0002] Steel for saw blades requires steel to have high hardness and strength, and has the advantages of high strength, good toughness and plasticity, and low cost. Saw blade steel is generally used to make the matrix of various saw blades. In order to obtain excellent mechanical properties, its heat treatment system is relatively strict. In order to produce steel for saw blades that meets the requirements of narrow composition control for subsequent steel rolling heat treatment, it is difficult to produce. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a steel for saw blades, which meets the requirement of narrow composition control for subsequent steel rolling heat treatment.

[0004] Technical scheme of the present invention is as follo...
