What is the production process of 1.8928 material composition

The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with 1.8928 material composition good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.

42CrMo4 material is an alloy structural steel with high strength, high hardenability, good toughness, small deformation during quenching, and high creep strength and endurance strength at high temperatures. 42CrMo4 steel is a modified AISI 4140 steel. The 1.8928 material composition product is mainly used in the manufacturing of seamless hydraulic cylinder or gas cylinder, heavy machinery, cranes, excavators and forklifts, etc.

Advantages of 1.8928 material composition, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.

Chromium element (Cr element) can improve the strength and hardness of 1.8928 material composition, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of 1.8928 material composition, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For 1.8928 material composition ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the 1.8928 material composition standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.

We are willing to cooperate sincerely with you with high-quality 1.8928 material composition products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services!
