Composition and properties
55S2A steel of high quality GOST 14969 equally can be classified as steels, spring purposes, and to high-carbon structural steels. The chemical composition of the material of the following:
| Alloying element | Carbon | Silicon | Manganese | Chrome | Nickel |
|---|---|---|---|---|---|
| The content in steel,% | 0,52 0,58… | 1,50 2,00… | 0,60…0,90 | To 0.30 | To 0.40 |
In addition to these components, the composition of the steel, there are also impurities: sulfur (not more than 0.02%) and phosphorus (not more than 0,030%).
Foreign counterparts of this are: in North America and Canada — steel 1.5026 ASTM 630 in Europe — steel 55Si7 DIN. Their composition is different from the domestic brands higher tolerances for sulfur and phosphorous content (up to 0,045% for each element), a high content of manganese (0,7…1,0%) and tighter tolerances on the content of silicon (1,5…1,8%). The presence of chromium and Nickel is not specified. Steel produced to order, so special review of their physical-mechanical indicators is not possible.
The domestic standards on the performance characteristics of steel 55S2A after heat treatment (quenching from 8700 C in oil and subsequent vacation at 4700 C) the following:
- The limit of temporary resistance, MPa — 1275;
- The plastic limit, MPa — 1174;
- Relative tensile elongation, percent — 6…7;
- The relative narrowing, % — 30;
- Brinell hardness number, HB — 240…285 (smaller values correspond to the annealed steel).
This data cannot be used for the manufacture of welded structures. Bulk rolled 55S2A, 55Si7, (1.5026) is insensitive to the formation placenow during hot forging blanks, not noted also the phenomenon of temper embrittlement.
Application
Spring structural steel type 55S2A, 55Si7, (1.5026) lend themselves well to forging in a hot condition at a temperature of the initial billet 850…8800 C. Therefore, they are widely used for the production of large springs in railway and heavy transport. Partly from this rental also receive the cutting knife, guard and guide sheet shears with inclined blade.
The most popular profiles are round bars and wire (diameter 5 to 300 mm), as well as square sizes from 5x5 up to 240x240 mm.
