GOST 2283-79. Cold-rolled strips of tool and spring steel. Specifications
Buy a spring tape, which meets the technical requirements of GOST 2283−79, is offered by Electrovek-Steel. Products are sold to economically advantageous prices from manufacturers. The supplier ensures the delivery of the products to any point specified by the customer.
GOST 2283−79 applies to a strip of spring steel, which is intended for the production of springs, measuring tapes and other products, to which similar operational requirements are imposed.
The tape is made of steel 65G GOST 1050−90, the chemical composition of which must correspond to the following:
Carbon,% — 0,62… 0,70;
Silicon,% — 0,17… 0,37;
Manganese,% — 0.90… 1.20;
Nickel,% — no more than 0,40;
Chromium,% — no more than 0,25;
Copper,% — no more than 0,25.
As the metallurgical impurities, the presence of sulfur and phosphorus (not more than 0.04% for each of the elements) is allowed.
The thickness of the tape — 0,6… 4,0 mm, width — 30… 450 mm.
The standard provides for the following classification of the tape for precision manufacturing. By thickness:
Normal accuracy, increased accuracy — T, high accuracy — V. Width:
Normal accuracy, increased accuracy — W
By type of surface: light — C, bright with colors of tarnishing — C, dark.
The company Electrovek-steel offers to purchase at the manufacturer’s prices spring tape GOST 2283−79. The supplier guarantees the timely delivery of products to the address specified by the consumer.
