| E335+S E335GC | 1.0060 1.0543 | Carbon steel derived from the E335 type of the standard EN 10025-2; the addition of sulfur confers greater machinability by chip removal. Not suitable for hardening heat treatments. | |
| S235JR S235JRC | 1.0038 1.0122 | This basic steel with a low carbon content, present in the regulations since the beginning of the varied standards (Aq37, Fe37, Fe360, S235), is still widely used thanks to its versatility as it can be welded, bent, deformed, and worked in a variety of ways. Not suitable for heat treatments. | |
| S355J2 S355J2C | 1.0577 1.0579 | Carbon steel present in the European standard EN 10025-2 as S355, it has a very high resilience even at low temperatures. Widely used for the production of flanges and fittings and for construction in general. Not suitable for hardening heat treatments. | |
| QUALİTY | WNR. | DESCRİPTİON | |
| C4C | 1.0303 | Steel with a very low carbon content, intended for the cold forming of very deformed and difficult-to-obtain small parts. | |
| C10C | 1.0214 | Low carbon steel with a chemical composition specially designed for cold deformation. The pieces obtained are generally subjected to carburization and tempering. | |
| 100Cr6 | 1.3505 | Base steel for the production of balls, rollers and rings for bearings, and for all small parts that must be subjected to localized and repeated loads. The high carbon and chromium content allows high hardness and perfectly transformed structures to be obtained after tempering. When it must be machined by chip removal or cold deformation, it must always be provided at the globulization annealing state. | |

| A105 K105 | – | A carbon steel in accordance with US standards, it has a very high resilience even at low temperatures. Used for flanges, fittings, and construction in general. | |
| 42CrMo4 | 1.7225 | Steel produced at the quenched and tempered state according to the United States standard ASTM A-193, widely used for linkages and bolts destined for the oil industry. It is analytically similar to 42CrMo4 of the European standard. This version is produced at higher temperatures, has slightly lower resistance characteristics but greater plasticity. | |
| A193 B16 | – | A steel produced at the quenched and tempered state according to the United States standard ASTM A-193, it is used for linkages and bolts destined for the oil industry. Analytically similar to the 40CrMoV4-6 type of the European standard EN 10269. It has greater temperability than the previous type thanks to the higher amount of alloy elements. | |
