AISI 4145H material properties are high tensile strength, stress resistance, wear and tear resistance, and hardness. AISI 4145H offers good wear and tear resistance in quenched and tempered conditions. AISI 4145H equivalent grade is SAE 4145H. AISI 4145H hardness is more as compared to other steel grades. AISI 4145H finds its application in industries such as the aircraft industry, automobile industry, automotive industry, defence industry, etc. AISI 4145H is a special grade with more hardness than AISI 4145. Heat Treatments such as normalizing, tempering, quenching, etc can be applied to AISI 4145H. It is used to make chains, screws, gears, arms, rollers and various other machine parts.

HARSH STEEL is the most prominent supplier of AISI 4145H steel. Buy good quality AISI 4145H round bar and AISI 4145H sheets from us which are tested for a variety of parameters and delivered with a material test certificate for complete quality assurance.

AISI 4145H Chemical Composition

The Chemical Composition of AISI 4145H contains a medium level of the carbon content of 0.42-0.49 %. The material has an Mn content of 0.65-1.10 % which imparts hardness to the material. The contents of P is reduced to 0.035% and S is reduced to 0.040 % max as excess content of P and S can damage the quality of steel and can cause the alloys steel to break at low stresses. The SAE 4145H has Ni and Mo content along with Cu.

AISI 4330V – description

High strength steel used in applications involving shock loading or stress concentration, for example drilling jars in oil and gas sectors or air frames and fasteners in aerospace industry. AISI 4330V is basically AISI 4330 steel with strength and hardenability improved by the addition of vanadium. The type of 4330 steel with a significant addition of nickel is called "4330 mod."

AISI 4330V STEEL FORGING

• Initial Forging Temperature:1150-1200°C

• Final Forging Temperature:>850°C

• Heating Rate:Strictly control the heating speed, which should be uniform and stable to

prevent cracking caused by improper heating.

• Holding Time:Ensure that the material is fully and evenly heated, and the holding time

should not be too long or too short.

• Forging Ratio:above 4:1

• Post-Forging Treatment:According to our experience, 4330V steel has extremely high

sensitivity to white spots, so dehydrogenation annealing after forging is a necessary heat treatment process.

AISI 4330V STEEL HEAT TREATMENT

• Normalizing:900-920°C, Cool in air.

• Annealing:830-860°C, Cool in furnace, Hardness Max 241 HBW.

AISI 4330V STEEL SUPPLY FORM & SIZE & TOLERANCE

• Hot Forged Round bar:Φ80-Φ1000mm
• Hot Rolled Round bar:Φ16-Φ160mm
• Heat treatment:Quenched and Tempered (+QT), Normalizing (+N), Annealing (+A)
• Surface finish:Black / Rough turned / Peeled

ALLOY STEEL 4130

SAE 4130 material properties include high hardness and tensile strength. Its hardness is credited to the high chromium content in the material. Typical applications for 4130 steel bar stock include:

Parts that are used under high stress such as pumps

Valve bodies

Fittings

Chassis

Body work panels for Aircraft & Automotive vehicles

SAE 4130 QT round bars and forged bars are also available of superior strength. AISI

4130 steel technical datasheet and SAE 4130 tempering curve data predict that the

material can be performed with heat treatments such as quenching, tempering,

annealing, and normalization.
