The production process of hardox 400 welding

BEBON is a large steel group with finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. We are committed to creating a various culture system with its own characteristics, and work hard to create a first-class steel plate company in China. Based on the business philosophy of quality-oriented and strengthened management, the company continues to develop in this industry.

The capital letter H in S355J0H and S355J2H stands for ""Hollow section"", which respectively represents the pipe of S355J0 and S355J2.The Executive Standards of S355J0 steel and S355J2 steel, HARDOX 400 welding are both EN 10025-2, the difference is that they have different temperature requirements for impact energy: S355J0 - impact energy at 0 ℃ is required to be ≥ 27J. S355J2: impact energy at - 20 ℃ is required to be ≥ 27J.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched HARDOX 400 welding increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of HARDOX 400 welding during tempering, while tempering determines the performance and life of the workpiece.

Chemical composition of 12Cr1MoV alloy steel plate: Carbon C: 0.08-0.15; Silicon Si: 0.17-0.37; Manganese Mn: 0.40-0.70; Sulfur S: allowable residual content ≤ 0.035; Phosphorus P: allowable residual content ≤ 0.035; Chromium Cr: 0.90-1.20; Nickel Ni: allowable residual content ≤ 0.030; Cu: allowable residual content ≤ 0.030; V: 0.15-0.30; Mo: 0.25-0.30.Delivery status of HARDOX 400 welding, 12Cr1MoV alloy steel plate: delivered in heat treatment (normalizing, annealing or high temperature tempering) or non heat treatment status, and the delivery status shall be indicated in the contract.

BBN Steel Company adheres to the marketing concept of "first-class technology, first-class steel quality, and first-class logistics services". It is our goal to build high-quality carbon steel HARDOX 400 welding, alloy steel plates and high-strength structural steel plate international-class boutique bases. Our logistic team will make customs clearance documents, track products production process, and update shipping information for customers. Creating value for customers is our pursuit.

It is a modern high-tech professional enterprise integrating scientific research, HARDOX 400 welding production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as HARDOX 400 welding process technology development, technology transfer and related technical consulting and technical services.
