Boiler and spring steel
Buy sheet steel of boiler steel stamps 12K, and spring steel with high carbon content, the company offers Electrocentury-steel. Prices — from a supplier that is prompt delivery of the metal at the address specified by the consumer.
Composition and properties
Steel stamps 12K according to GOST 5520−79 has the following chemical composition:
|Availability in steel, %||0,08…0,16||0,17…0,37||0,4…0,7||To 0.30||To 0.30||To 0.6|
As impurities steel contains 12 To up to 0.04% sulphur and phosphorus, and up to 0.08% of arsenic.
Foreign analogues of this steel are: North America — steel А285 in Western Europe — steel 1.0345.
The practical range of section dimensions of supplied rental: width — 6…240 mm, genuine — from 1500x4200 to 5000x18000 mm. Deliveries are made in the form of rolled plate blanks and the tubular sections. Delivery options include steel with low or normal degree of oxidation (degree A, b and C), respectively, with normal or reduced strength. 12K steel in hot-rolled condition it lends itself well to diffusion welding without the use of specific technologies and heating the joined workpieces.
The main physico-mechanical characteristics:
- Tensile strength, MPa — 350…440;
- The plastic limit, MPa — 205…225 (smaller values correspond to the rental sheet);
- Elongation, percent — 24;
- Impact strength, kJ/m2 — 780.
12K steel used in the manufacture of boilers, industrial water heaters and other vessels that work under pressure and in conditions of normal, low and high… up to 180 200C temperature. Easy separation operations, cold forming, pre-annealing is not required.
Sheet and bulk rolled spring steel with a high carbon content material provides the appropriate indicators of its strength and elasticity.
The company Electrocentury-steel offers steel 12K at factory prices. This provides a wide range profiles with appropriate parameters. Delivery according to the specifications of ASTM, EN 10028, and the DIN was 17155 holding, if necessary tests. Each batch of products is accompanied with quality certificate.
