What is USt37-2 carbon steel plate sheet machinability

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of USt37-2 carbon steel plate sheet steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special USt37-2 carbon steel plate sheet materials and specifications can be ordered in advance.

EN10028-2 16Mo3 grade is an alloy steel plate for pressure vessels. EN10028-2 specified grades of 16Mo3 chromium-molybdenum steel alloys, which are used for materials at elevated operating temperatures and are used as weldable steel in industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries. Our USt37-2 carbon steel plate sheet steel plates are usually delivered in normalized condition. According to the negotiation between the supply and demand sides, it is not necessary to process the state delivery.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the USt37-2 carbon steel plate sheet and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This USt37-2 carbon steel plate sheet method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
