The carbon tool steel thick plate is made of carbon tool steel and is made by hot rolling. This carbon tool steel has good cold and hot processing performance, high hardness and plastic resistance, low production cost and wide range of uses. q355gnh size in inches, Carbon tool steel is usually delivered in an annealed or high temperature tempered state. It is mainly used to manufacture cutting tools, measuring tools and molds with low cutting speed, simple shape and low precision. The thickness of the steel plate is 4.5-25mm, and the width and length comply with GB709 regulations.

The q355gnh size in inches processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the q355gnh size in inches steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. q355gnh size in inches, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
