What is H 11 steel?

H11 is an AOD + VAR, hot work, chromium tool steel with low carbon and good toughness. This alloy has the ability to deep harden by air quenching. The low carbon and toughness makes this alloy appropriate for highly stressed structural parts within the aerospace industry.

What is SKD61 material?

SKD61 is the tool steel, mold steel, and middle carbon steel possessing high hardness and wear resistance after heat treatment. It also has the good performance of hardenability and thermal fatigue stability.

What is H11 in chemistry?

H11 alloy is a 5% chromium hot-work tool steel characterized by its incredible impact toughness and good red-hardness. The alloy is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment.

What is the difference between H11 and H13 steel?

If we compare between H11 and H13, H11 tool steel consists of less vanadium than the commonly used H13 hot work tool steel. This gives H11 steels the higher toughness, with some reduction in wear resistance and tamper resistance.

What is D2 steel hardness?

between 54 – 61 HRC
D2 can reach an approximate tempered hardness range between 54 – 61 HRC and features an approximate compressive yield strength of around 275 ksi to around 319 ksi as hardness increases.

What is difference between D2 and D3 material?

Type D3 steel is oil-quenched; though small sections can be gas quenched after austenitization using vacuum. As a result, tools made with type D3 steel tend to be brittle during hardening. Type D2 steel is the most commonly used steel among the group D steels.

What is AISI H13 steel?

AISI H13. AISI H13 tool steel is characterized by good resistance to thermal softening, high hardenability, high strength, and high toughness. This steel has therefore been widely used to produce many different types of hot working dies, such as forging dies, extrusion dies, and die-casting dies.

What is H12 steel?

ASTM/AISI H12 Steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatmnet. H12 tool steel material has good resistance to thermal fatique cracking (heat cracking) and excellent resistnce to gross cracking and thermal shock when water cooled in service.

Is H11 better than H13?

Testing HEPA filters with smoke and a small particle generator. H13 HEPA filters perform better than True (H10-H12) HEPA filters.
