BBN supply A572 Grade 42 HSLA Steel cold working and aging

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality A572 Grade 42 HSLA Steel products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

We supply more than 2,000 tons of high strength A572 Grade 42 HSLA Steel low alloy steel coils to support the construction of Iraq's thermal power equipment projects. As a "Belt and Road" construction project, the Iraqi thermal power generation project has high requirements on the quality of steel for power generation equipment. In particular, the flue gas baffle door sealing system of A572 Grade 42 HSLA Steel thermal power plants has extremely strict requirements on the composition, yield strength and tensile strength of steel. Our hot rolled low alloy steel coils have won the favor of customers for their excellent mechanical properties, standard sizes, and beautiful shapes.

The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate A572 Grade 42 HSLA Steelis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

The company has our own truck fleet, and can transfer products flexibly and quickly. At the same time, we have large warehouses near the ports of Tianjin and Shanghai, so as to ensure that we can deliver high-quality products to customers in the first time. At the same time, it also greatly reduces the transportation cost, and realizes the double harvest of time benefit and economic benefit. Time guarantee is one of the important strengths of our service.

A572 Grade 42 HSLA Steel annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of A572 Grade 42 HSLA Steel annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. A572 Grade 42 HSLA Steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
