API 5L L450 PSL1 grade steel cold working

In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and API 5L L450 PSL1 grade steel 47.521 million tons of South Korea. In the first quarter, the global output was 311 million tons, with a year-on-year decrease of 0.5%, with China API 5L L450 PSL1 grade steel increasing by 2.4%; the overseas output decreased by 5.4%, Among them, EU decreased by 9.2%, Japan increased by 1.3%, India decreased by 7.7%, CIS increased by 2.1%, and South Korea decreased by 4%.

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API 5L L450 PSL1 grade steel and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

Q215 steel has good plasticity and weldability. Q235 steel has certain strength, plasticity, toughness and weldability. Q235 steel is easy to punch and can meet the use of steel structure. Q255 steel has high strength, good plasticity and weldability, and its application is not as extensive as Q235 steel. Q275 steel has high strength, poor plasticity and weldability. Q275 steel is used for shafts, connecting rods, gears, keys and metal components with high strength requirements.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.

After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of API 5L L450 PSL1 grade steel, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.

Keep close relationship with all manufacturers and users, cooperate sincerely, share weal and woe together. We are deeply tolerant of travelling with you! We value and value each other's career and friendship. No matter when and where, all our staff will spare no effort to put into the work, and do their best to provide API 5L L450 PSL1 grade steel satisfactory services for all friends, so as to achieve win-win and multi win for each other.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication.
