SA299GrB steel plates with a thickness of less than or equal to 50mm are usually delivered in the rolled state, and can also be delivered in the state of normalizing, stress relief, or normalizing plus stress relief. Steel plates with a thickness greater than 50mm should be normalized heat treatment. It can also add flaw detection standard requirements, flaw detection level requirements, alloy element composition control requirements, etc. according to needs.
Weathering steel plate A514 grade H alloy steel plate for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate A514 grade H alloy steel plate has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.
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 A514 grade H alloy steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A514 grade H alloy steel plate during tempering, while tempering determines the performance and life of the workpiece.
We have a professional production team and high-quality production equipment, and we also have a great A514 grade H alloy steel plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the A514 grade H alloy steel plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.
The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
