1.7220 chemical composition quality control

For the 1.7220 chemical composition construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that 1.7220 chemical composition steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.

Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life. The annual Spring Festival Gala in 2019 was held on January 20, 2020. There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products 1.7220 chemical composition are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

In the process of 1.7220 chemical composition steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose 1.7220 chemical composition different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.

The common delivery status of 1.7220 chemical composition, SA516 Gr 70 plate is as follows:
1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point.
2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air).
3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly.
4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

The high strength 1.7220 chemical composition low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of 1.7220 chemical composition ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
