nm400 weathering steel equivalent in indian standard

In actual processing applications, the processing NM400 weathering steel thickness of flame cutting ranges from 6 to 200 mm, and the NM400 weathering steel cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting NM400 weathering steel with a certain thickness above 10mm.

Classification of NM400 weathering steel, steel plate, including strip steel: 1. Classified by thickness: (1) thin plate (2) medium plate (3) thick plate (4) extra thick plate 2. Classification by production method: (1) hot rolled steel plate (2) cold rolled steel plate 3. Classification according to surface characteristics: (1) galvanized sheet (hot galvanized sheet, electro galvanized sheet) (2) tin plate (3) composite steel plate (4) color coated steel plate 4. Classification by use: (1) bridge steel plate (2) boiler steel plate (3) shipbuilding steel plate (4) armored steel plate (5) automobile steel plate (6) roof steel plate (7) structural steel plate (8) electrical steel plate (silicon steel sheet) (9) spring steel plate (10) others

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, NM400 weathering steel high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of NM400 weathering steel wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.
