Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional A514 grade M alloy steel plate production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of A514 grade M alloy steel plate leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
Boiler steel plates are mainly used to manufacture various boilers and important accessories. Because the boiler steel plate is working under medium temperature (below 350°C) and high pressure, in addition to high pressure, it is also subject to impact, fatigue load and water and gas corrosion. It is required to ensure a certain strength and also have good welding and cold bending performance. Common grades: Q245R, A515 Grade 55, A515 Grade 60, A514 grade M alloy steel plate, A516 Grade 65, A516 Grade 70.
In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials A514 grade M alloy steel plate used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.
The fake and inferior A514 grade M alloy steel plate, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.
There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. A514 grade M alloy steel plate, ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another A514 grade M alloy steel plate magnificent projects.
The results of adopting two-level A514 grade M alloy steel plate service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and A514 grade M alloy steel plate after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
