Spring belt

In spring alloy, silicon, manganese, chromium, vanadium and molybdenum elements with appropriate amounts are used. Spring belts have acceptable tensile strength. Spring belts also have anti-wear properties. The presence of silicon in the spring belts increases the elasticity and the presence of the cream increases the strength and corrosion resistance.

The presence of elasticity in spring steel helps to be able to deform to a suitable level when the steel is under high pressure, and this ability also increases the tensile strength of these steels.

Spring belts are available in different thicknesses.

The main material of this type of belt, as their name suggests, is spring steel, which is also used to produce various springs;

Spring steel 1,8159 is used in the production process of multilayer springs – helical, flat and springs of twisted shafts as well as spring belts (spring belts up to 30 mm thick and round springs up to 40 mm in diameter) and for high temperature work. (Up to about 300 ° C) is also suitable.

Ck75 spring steel with standard number 1.1248 is used to prepare spring belts with dimensional accuracy and high quality.

A special type of spring steel that has 15.64% chromium, 4.38% nickel, 2.68% molybdenum, 1% manganese, 0.32% silicon, 0.12% copper and 14% carbon, in the manufacture of jet engine springs And other items that require high heat resistance are used.

Among the widely used spring steels for making spring belts, we can mention Ck60 or 1.1221 and Ck70 steels.
