S1 is a shock-resistant tool steel in the AISI S-series. It is an oil-hardening steel designed for applications requiring high impact toughness combined with moderate wear resistance.
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.40–0.55 |
| Silicon (Si) | 0.15–1.20 |
| Manganese (Mn) | 0.15–0.50 |
| Chromium (Cr) | 1.00–1.80 |
| Tungsten (W) | 1.50–3.00 |
| Vanadium (V) | 0.15–0.30 |
| Phosphorus (P) | ≤0.03 |
| Sulfur (S) | ≤0.03 |
S1 tool steel is widely used for tools subjected to repeated impact loads, including:
| Grade | Toughness | Wear Resistance | Typical Use |
|---|---|---|---|
| S1 | Excellent | Moderate | Impact tools |
| S7 | Outstanding | Moderate | Heavy-duty impact dies |
| O1 | Good | Good | General-purpose tools |
| A2 | Medium | High | Precision dies |
| D2 | Low | Very High | Long-life cutting dies |
DIN 1.2550 is the European material number for a shock-resistant cold work tool steel and is widely recognized as the closest European equivalent to AISI S1. Depending on the standard or manufacturer, you may also see it designated as 60WCrV8 (EN ISO 4957) or 60WCrV7 (older DIN designation).
| Standard | Grade / Designation |
|---|---|
| EN ISO 4957 | 60WCrV8 |
| DIN (older) | 60WCrV7 |
| AISI/SAE (USA) | S1 |
| ASTM A681 | S1 |
| W.-Nr. (Material No.) | 1.2550 |
| GB (China) | 6CrW2Si (closest equivalent) |
| GOST (Russia) | 5ХВ2С (5KhV2S, approximate) |
| ÖNORM (Austria) | K455 (designation) |
The raw materials for Tool Steel Grade S1 Round Bars are sourced from certified suppliers and undergo rigorous inspection. Each batch is verified for chemical composition and mechanical properties against ASTM A681 standards to ensure compliance with the required specifications. This includes checking for carbon content, chromium, and vanadium levels, ensuring that the material meets industry standards.
The forming process involves hot working the steel at temperatures between 1100°C to 1200°C to achieve the desired shape and size. The round bars are extruded or forged to precise dimensions, typically ranging from 10 mm to 200 mm in diameter, with tolerances adhering to ASTM A276 standards. This process ensures the integrity and uniformity of the bars, making them suitable for various applications.
| Process | Temperature (°C) | Medium | Purpose |
|---|---|---|---|
| Quenching | 850 | Oil | Increase hardness |
| Tempering | 200 | Air | Reduce brittleness |
Quality inspection and testing are integral to our manufacturing process. Each batch of Tool Steel Grade S1 Round Bars undergoes various tests including PMI (Positive Material Identification), hardness testing, and hydrostatic testing.
