The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

There are eight different grades of products under the ASTM A514 TYPE standard: A514GrA, A514GrB, A514GrE, A514GrF, A514GrH, A514GrP, A514GrQ, A514Gr.S. ASTM A514 steel plate has high strength, good cold forming performance and welding performance; high toughness and low brittle transition temperature; it has good corrosion resistance and wear resistance. ASTM A514 steel plate HARDOX 400 steel specification as a structural steel plate is widely used in the United States and foreign markets.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than HARDOX 400 steel specification. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel HARDOX 400 steel specification is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between HARDOX 400 steel specification, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.

The company has our own truck fleet, and can transfer products flexibly and quickly.
