Home > Tablet Toolings > Tool Steel

For tool steel – toughness, resistance to wear & corrosion, strength & resistance to distortion & warping during heat treatment are its most important properties. These properties are the condition under which it is manufactured. For purpose of comparison, the steels used to manufacture tablet press toolinghave been categorised below:

O1 STEEL

It is a General Purpose Steel which is a Oil Hardened Non Shrinking Steel which has High Hardenability and is commonly used for Blanking & Stamping Punches.

S7 STEEL

Is a tool steel grade with exceptional impact resistance plus the highest hardenability of shock resisting grade of Tool Steel due to which is commonly used in Tablet Compression Punches for its heavy load bearing capacity.

D3 STEEL

Is a Hot Die Steel and comes under the Category of High Carbon High Chromium (H.C.H.C.) Steel which has Great Resistance to Wear due to the percentage of Chromium in its structure for which it is also the most preferred choice for Tableting Dies.

D2 STEEL

It comes under High Carbon High Chromium (H.C.H.C.) Steel category which also has Excellent Wear Resistance & Abrasion Resistance and so is generally used for Abrasive Tablet Compression.

A2 STEEL

Is a Cold work Steel and is a Air Hardening Steel which provides High Hardness with good dimensional stability which also averages better Wear Resistance.

S1 STEEL

Is a Cold work Steel which has Tungsten in its Elements due to which it has Greater Toughness and Impact Resistance also can obtain High Hardness.

408 STEEL

Is a Stainless Steel which is a Ferritic Steel that ofers good mechanical properties which is Resistant to Corrosion and prevents rust corrosion cracking.

440C STEEL

Is a Stainless Steel type with High Carbon and High Chromium percentage of Elements which also has Excellent Hardenability and can go upto 60 HRC max. This category of Steel is used to Manufacture Small Tips for Multi Tip Tooling ’s.

SP10 STEEL

Is a primarily a Oil Hardening Grade Steel which was developed for Better Resistance to Shock that has Good Elemental combination of Manganese-Silicon-Molybdenum.

K340 STEEL

Is a Premium Cold work Steel which has High Yield Strength and good Toughness properties which is suitable for Chipping & Premature Wear issues also has Excellent Compressive strength.

M340 STEEL

It is a Premium Steel with Chromium content of upto 16% to 18% which helps in obtaining least Ra value on the surface giving the surface a mirror finish which make it very less Coeicient to friction.

N690 STEEL

Is a Premium Steel with Chromium content similar to the PK5 Steel with the addition of Cobalt in it which bonds the molecular structure uniformly giving it Greater Surface finish and Longer Durability.
