4140 steel flat bars: 4140 Steel In Metal Sheets & Flat Stock for sale | OTAI

What is 4140 steel

4140 steel is a cold drawn annealed steel of relatively high hardenability with its chromium content providing good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.

4140 alloy steel well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 steel has good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures.

One of our customers Peter from Phillippine sent us an inquiry for 4140 steel flat bars. As time is tight, he needs to receive these 100 tons of 4140 steel within 40 days. That’s no problem for us because we keep a daily inventory of 1500 tons.

42crmo4 Steel Flat : 42crmo4 Alloy Steel – Flat Bar, Cut to Size | OTAI

What is 42crmo4 steel

42crmo4 is low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In 42crmo4, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel. The additions of chromium and molybdenum are why 42crmo4 is considered “Chromoly” steel.

Why Choose OTAI

What is 42crmo4 steel

42crmo4 is made by placing iron, carbon, and other alloying elements into an electric furnace or oxygen furnace. The major alloying elements added to 42crmo4 are: Chromium Manganese Molybdenum Once the iron, carbon and other alloying elements have been mixed together in liquid form, it is allowed to cool. The steel may then be annealed; possibly several times.

The additions of chromium and molybdenum are why 42crmo4 is considered “Chromoly” steel.

1)  42crmo4 steel belongs to the alloy structural steel. After Quenching & Tempering, its hardness is 28-34 HRC.

2) 42crmo4 steel used for bending machine molds.

3) Besides, it can be used to under 2000m deep well of oil drill pipe joint and the fishing tool.

4) Also, it can be used for engineering structural parts, like high tensile shafts, gears, pinions, and spindles.

42crmo4 hr plate: Its heat treatment has good strength and good comprehensive mechanical properties.

The common stainless steel’s chromium content is higher than 12.5%. So it has anti-rust performance. From the analysis of the composition, 42crmo4 steel also has chromium. But its chromium content is only 0.8%-1.1%, which is far lower than the standard for rust prevention. Therefore, 42crmo4 steel is not stainless steel. Please pay attention to its rust prevention when using it.

But 42crmo4 steel can be used to make gears. Because lubricating oil is often used when gears are running. The lubricating oil can protect the gear from rust while protecting the normal operation of the gear.

A2 steel/1.2363 is a German Cold work tool alloy steel material grade.

A-2 steel is an air hardening alloy chromium-molybdenum-Vanadium die steel. As cold work steel, its grade contains 5% chromium. In applications that require greater size stability, A2 steel is preferable to O1 tool steel.

Advantage of A2 steel in repair welding operation: since the preheating and post-heating temperature is lower than SKD11, repair welding operation is easier.

A typical application such as blanking die, the molding dies, blanking dies, stamping die, stamping die, die, extrusion die, boxing, shear knife blade, instrumentation, knurling tools, volume, head, and machine parts. (A2 steel flat bars)
