stocks H13 steel in flat, square and round bar. We provide steel in all sizes as your requirements. Consult our team who will assist you for any query related to H13 steel.

SAE/ AISI H13 tool steel equivalent with JIS SKD61, GB 4Cr5MoSiV1 and DIN 1.2344 Tool Steel. AISI H13 steel consists of chromium, molybdenum and vanadium and is known for its high hardenability and great toughness.

The molybdenum and vanadium act as strengthening agents while the chromium content helps the AISI H13 steel to withstand softening when used at high temperatures. It also combines shock and abrasion resistance, has good red hardness, can resist rapid cooling and withstand premature heat checking.

H13 Tool Steel has high hot-wear resistance abilities along with great strength, heat conductivity and invulnerability to hot cracking. It has good resistance to abrasion at each low and high temperature. It displays high level of toughness and ductility. The H13 steel has Uniform and high level of machinability and polish ability. It has high-temperature strength and resistance to thermal fatigue, glorious through-hardening properties and shows very limited distortion during hardening.

H3 ESR is the most purified material with the conventional VD route. The nature of material increase the strength, exceptionally increase the micro-cleanness level. H13 ESR tool steel is most refined, has greater homogeneity and an exceptionally fine structure, resulting in improved machinability, polishing & high temperature tensile strength. Exceptionally suggest the use of AISI-H13 ESR grade for Aluminium Pressure Die Casting and other part subjected to high working temperatures and high weight quality. H13 steel is completely ultrasonic examined with 100% positive outcomes according to NDT standards.
