What is S 7 tool steel?
General Purpose Grade Air-Hardening Tool Steel. AISI S7 is a shock resisting general purpose air-hardening tool steel. The shock absorbing properties provide excellent impact resistance and high strength and toughness. In addition, S-7 has good resistance to softening at moderately high temperatures.
What Rockwell is S7?
S7 Steels Mechanical Properties
| Properties | Metric |
|---|---|
| Hardness, Rockwell C (air cooled from 941°C, 449°C temper temperature) | 53 |
| Hardness, Rockwell C (air cooled from 941°C, 149°C temper temperature) | 57 |
| Modulus of elasticity | 207 GPa |
| Charpy impact (V-notch; air cooled from 941°C; 425°C temper temperature) | 13.6 J |
How strong is S7 tool steel?
S7 tool steel properties S7 is comparatively less resistant to wear but is very tough. It resists distortion during heat treatment well. It is the softest of the steel formulations compared in this article, achieving a typical working hardness range between 48 – 58 HRC.
What type of steel is tool steel?
carbon alloy steel
Tool steel is a type of carbon alloy steel that is well-matched for tool manufacturing, such as hand tools or machine dies. Its hardness, resistance to abrasion and ability to retain shape at increased temperatures are the key properties of this material.
What type of material is S7?
S7 Shock-Resisting Tool Steel is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes it a candidate for a wide variety of tooling applications. It can be used successfully for both cold and hot work applications.
What is S7 steel made of?
Chemical Composition
| Element | Content (%) |
|---|---|
| Iron, Fe | 93.85 |
| Carbon, C | 0.45-0.55 |
| Manganese, Mn | 0.20-0.80 |
| Silicon, Si | 0.20-1.00 |
Is S7 tool steel cast or forged?
AISI S7 tool steel is a shock-resistant air hardening steel. AISI S7 steel has exceptional impact properties plus the highest hardenability of shock resisting grades of tool steel. Steel S7 also possesses good softening resistance at high temperatures which gives it hot work capabilities.
What is S7 material?
What is the hardness of tool steel?
Properties of Tool Steels — Hardness Hardened cold work tool steels are generally about 58/64 HRC (hardness Rockwell C), depending on the grade. Most are typically about 60/62 HRC, although some are occasionally used up to about 66 HRC.
What is tool steel composition?
The four major alloying elements that form carbides in tool steel are: tungsten, chromium, vanadium and molybdenum. The rate of dissolution of the different carbides into the austenite form of the iron determines the high-temperature performance of steel (slower is better, making for a heat-resistant steel).
