usage of nm450 sheet structural vs boiler steel plate

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel usage of NM450 sheet products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the usage of NM450 sheet market and has strong competitiveness.

Shipbuilding steel is a kind of steel plate used by shipyards, shipbuilding companies and dockyards to manufacture hulls of cargo and passenger ships, boats, offshore drilling platforms, gateways and other structures and vessels. The company also supply AB AH36 plates and steel sheets usage of NM450 sheet in coils or cut to length, steel profiles (steel bulb flats, rounds and squares), and round and profiled tubes made from shipbuilding steel grades. Shipbuilding steel is produced under the control of certifying societies, sea and river registers.

The main metal material usage of NM450 sheet used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than usage of NM450 sheet. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel usage of NM450 sheet is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

usage of NM450 sheet, Q460D quenched and tempered steel plate spot specification: 6*2000*8500, 6*2000*10800, 45*1550*4900, 16*2000*9700, 14*1950*7030, 22.23*2181*12200, 28*2010*7300, 23.83*2179*5000, 19*2500*6000, 23.83*2179*5000, 28.58*2171*12300, 28.5*2340*12150, 28.58*2171*11500, 28.58*2171*10800, 22.23*2150*12200, 28.5*2000*12150, 28.58*2172*11500, 28.58*2172*10800, 28.58*2172*12100, 25.4*2298*13000 (mm).

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent usage of NM450 sheet products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the usage of NM450 sheet technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
