Ventura Alloy and Steels supplies and stocks H13 tool 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 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 H-13 tool 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. H13 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 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 Aluminum Pressure Die Casting and other part subjected to high working temperatures and high weight quality. H13 is completely ultrasonic examined with 100% positive outcomes according to NDT standards.

 

Steel Properties:

• Great toughness

• Thermal conductivity

• High hot-wear resistance

• Hot tensile strength

• Insusceptible for hot cracking (Hot Crack resistant)

• Can be water-cooled to a restricted degree

We are offering EN 47 Spring Steel Wire to our clients.

Chemical Composition - (Typical Analysis in %)

VENTURA EN47 Chromium Vanadium type spring steel supplied in the as rolled condition as well as spheroidized annealed condition. EN47 is suitable for oil hardening and tempering. When used in the oil hardened and tempered condition EN47 spring steel combines spring characteristics with good wear and abrasion resistance. When hardened EN47 offers excellent toughness and shock resistance which make it a suitable alloy spring steel for parts exposed to stress, shock and vibration.

Forging:

Forge at 1050°C. Do not work this steel when it has fallen below 840°C.

Annealing:

Heat slowly to 820-840°C, soak well. Cool slowly in the furnace. (Our annealing is done in electric furnace to avoid decarburization)

Hardening:

Pre heat slowly to 650/700°C and thoroughly soak. Continue heating to the final hardening temperature of 830/860°C and allow the component to be heated through. Quench in oil.

Tempering:

Temper the EN47 spring steel component immediately after quenching whilst tools are still hand warm. Re-heat to the tempering temperature then soak for one hour per 25 millimetre of total thickness (2 hours minimum) Cool in air. For most applications tempering of this grade will be between 400-600°C.

Heat Treatment:

Heat treatment temperatures, including rate of heating, cooling and soaking times etc. will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and workpiece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of EN47.
