What grades are tool steel?

What grades are tool steel?

Tool Steel Grades and Corresponding Applications The AISI-SAE general purpose grades of tool steel are O-1, A-2, and D-2. These standard grade steels are considered “cold-working steels,” that can hold their cutting edge at temperatures up to about 400°C.

What is 10 V steel?

CPM 10V is a unique tool steel made by the Crucible Particle Metallurgy process. It is designed with a tough, air hardening base analysis with added high carbon and vanadium for exceptionally good wear resistance, toughness and strength for cold and warm work tooling applications.

Which steel is best for tools?

W-grade steel is essentially high carbon plain-carbon steel. This group of tool steel is the most commonly used tool steel because of its low cost compared to others. They work well for parts and applications where high temperatures are not encountered; above 150 °C (302 °F) it begins to soften to a noticeable degree.

What is P20 tool steel?

P20 tool steels are nitrided or carburized. These steels are capable of being machined into complex and large dies and molds. P20 steels are mostly used in the carburized condition. The presence of chromium and nickel enhances the toughness and hardness of P20 steels.

How hard can S7 tool steel get?

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.

How hard can A2 tool steel get?

A2 tool steel is an air hardening, cold work steel. A2 is a 5% Chromium steel which provides high hardness after heat treatment with good dimensional stability. It is heat treatable and will offer a hardness in the range 57-62 HRC.

What is 4V steel?

CPM 4V is a powder metal tool steel with an outstanding combination of properties including high impact toughness and very good wear resistance.

What is A11 tool steel?

AISI A11 tool steel is a high vanadium tool steel having wear resistance greater than most of the other tool steels, as well as good toughness and strength. It has improved response to heat treatment, easy grinding process and an expansion of about 0.0004 inches upon heating.

What is the difference between 4140 and 4130 steel?

4140 is similar in composition to 4130 except for the higher carbon content. The “30” in 4130 represents the carbon content by % of weight (0.28-0.33 % for 4130 vs 0.38-0.43 % for 4140). Because of its higher carbon content, 4140 steel has greater hardenability and strength than does 4130.

What is premium tool steel?

Premium Products Stock Sizes PSB22 is an air hardening cold work tool steel with an excellent combination of wear resistance, compressive strength, toughness, and temper resistance.

What is S7 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 is D2 tool steel?

D2 steel is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition.

What Rockwell is S7?
