Rolling Technical Standard of 35CrMo Steel

For the rolling of 35CrMo steel plate, the following standard requirements need to be met:
(1) Deviation requirements for thickness, width and length
The thickness, width and length deviation of 35CrMo steel plate should be within the standard range to ensure the appearance quality and dimensional stability of 35CrMo steel plate. The thickness deviation of 35CrMo steel plate is generally controlled within plus or minus 0.5 mm, the width deviation is not more than minus 2 mm, and the length deviation is controlled within plus or minus 10 mm.

(2) Surface quality requirements
Surface quality is an important indicator to measure the quality of 35CrMo steel plate products. The surface of 35CrMo steel plate should be flat, free from defects such as cracks and potholes, and the specularity and glossiness should meet certain requirements. For conventional 35CrMo steel plates, the surface should be smooth and bright, and the flatness and parallelism should meet the national standards.

(3) Mechanical property requirements
The mechanical properties of 35CrMo steel plate are directly related to the strength and plasticity of the product, and the mechanical properties of 35CrMo steel should meet the requirements of national standards. Among them, the yield strength and tensile strength of 35CrMo steel should meet the standard requirements and meet the requirements of impact toughness.

(4) Structural properties
The structural performance of 35CrMo steel plate can be evaluated by means of metallographic structure observation and microstructure analysis to ensure that 35CrMo steel plate can meet the specified application requirements.

The above standard requirements are the basic content of the rolling technical standard of 35CrMo steel plate. The corresponding technical specifications need to be adjusted and improved during production to meet market demand and improve the quality and use value of 35CrMo steel plate products.
