Boiler steel
The company Electrocentury-steel offers to buy boiler steel in an expanded range of thicknesses and diameters. The price is from the manufacturer. The supplier ensures prompt delivery of the whole batch of steel in the item specified by the client.
Composition and properties
The group boiler steels include low-carbon sheet steel with surface coating based on zinc. Supply of steel is produced mainly in rolls, with material thickness of 0.4−0.8 mm. the chemical Composition of such steels according to GOST 14918following:
| Item | Carbon | Silicon | Manganese | Chrome | Nickel | Copper |
|---|---|---|---|---|---|---|
| Content, % | To 0.06 | 0.03 | To 0.40 | traces | To 0.25 | To 0.20 |
As the metallurgical impurities are allowed no more than 0,035% of phosphorus and not more than 0,035% sulfur. On customer request, the boiler steel can be supplied with polymer-containing coating and coating based on zinc. Technology is used both hot and cold galvanizing.
Mechanical properties of boiler steels:
- Tensile strength, MPa — not more than 300;
- The plastic limit, MPa — not more than 190.
- Elongation % — 35.
- The relative narrowing, % — 65.
- Hardness on the Brinell hardness after annealing HB max — 126.
Cold-rolled boiler steel is the first and highest category of quality, the differences between them lie in the fact that for higher category may additionally include the ability of steel to very deep drawing (VG). Among the acceptable grades of boiler steel in the second group include steel stamps 08JU, rascislau aluminum. In the composition of this steel contains up to 0,2…0,4% of aluminum, by reducing the percentage content of manganese.
Buy low carbon boiler steel is offered by the company Electrocentury-steel. Prices — from the manufacturer. The supplier guarantees high quality and strict adherence to product range delivery products.
Application
Coils and long-length strips of sheet, boiler steel are used for production of steel elements of large tanks and boilers. Steel have a high capacity for drawing and other operations of plastic deformation. The material welded, and the presence of a corrosion-resistant coating provides adequate durability of the products. Delivery can be done with additional criteria for the uniformity of zinc coating and the nature of the surface pattern.
To buy boiler steel at the best, price — economical offer from the company Electrocentury-steel. The supplier guarantees high quality products. Each batch is accompanied by certificate of quality.
