What are the 34crmo4 alloy steel material steel definition advantages

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important 34crmo4 alloy steel material steel definition heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced 34crmo4 alloy steel material steel definition technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel 34crmo4 alloy steel material steel definition production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.

With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate 34crmo4 alloy steel material steel definition shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.

34crmo4 alloy steel material steel definition, Q345B low alloy steel plate composition:
1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%;
2) Add manganese-based alloying elements;
3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel;
In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

34crmo4 alloy steel material steel definition, ASTM A131 shipbuilding steel has different grade levels. The ordinary strength shipbuilding steel grades are grade A/B/D/E. Their min. yield strength is 235 Mpa, and tensile strength is 400-520 Mpa. The higher strength shipbuilding steel grades are grade AH32/DH32/EH32/FH32, AH36/DH36/EH36/FH36 AH40/DH40/EH40/FH40. The min. yield strength of AH32/DH32/EH32/FH32 steel is 315 Mpa, and tensile strength is 440-590 Mpa. The min. yield strength of AH36/DH36/EH36/FH36 steel is 355 Mpa, and tensile strength is 490-620 Mpa. The min. yield strength of AH40/DH40/EH40/FH40 steel is 390 Mpa, and tensile strength is 510-650 Mpa.

The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products 34crmo4 alloy steel material steel definition price concessions, rich industry experience, complete varieties.
