TOOL STEEL SERI S

TOOL STEEL SERI S

SHOCK – RESISTING TOOL STEELS

·        Carbon content = 0.5 – 0.6%. Alloying elements – Cr, W, Mo.

·         These are Characterized by good toughness, hardness and improved hardenability. These steels are generally, water or oil – hardened.

·         “Low temperature Tempering” is carried out where, toughness and hardness of the tool steel are of prime importance, otherwise “High Temperature Tempering” is preferred. 

·         Sllicon – manganese steels (0.55% C, 2.0% Si, 1.0% MNn) are included in this group. Due to their high Si – content, decarburization and grain coarsening takes place in these type of steels.

TOOL STEEL SERI S

SHOCK RESISTING TOOL STEELS ( S – SERIES) :

• These steels have 0.45 to 0.55% carbon. The alloys, silicon, and nickel are ferrite strengtheners. Chromium increases wear resistance and hardenability. The S – series of tool steels ware originally developed for chisel – type applications, but the number of alloys in this category has evolved to include steels with a broad range of tool applications. This class of steels has a very good shock resistant qualities with excellent toughness.

• They are used in from tools, chisels, punches, cutting blades, springs, timming, and swaging dies, concrete and rock drills, bolt cutters.
