4340 Alloy Steel Bar STOCK

A low-alloy steel known among industries for its toughness, the 4340 Alloy Steel is highly used in construction.

4340 ALLOY STEEL BAR STOCK

This nickel-chromium-molybdenum alloy steel is primarily used across industries also because of its ability to achieve high strengths in heat-treated conditions.

In fact, this type of alloy steel is able to maintain its great fatigue and wear resistance and is even immune to embrittlement.

As such, industries ensure that they acquire a 4340 alloy steel bar stock to be used in applications where its features are proven to be most useful.

4340 ALLOY STEEL IS APPLICABLE IN HIGH STRESS CONDITIONS

4340 steel is a high-quality alloy that is often used in producing gears. It has excellent resistance to wear and corrosion. 4340 steel is an alloy with a high percentage of chromium, making it a good material for resisting corrosion and wear. This makes it the perfect material for parts that need to last a long time, like gears and other components in machinery.

4340 alloy steel is Chromium-Molybdenum-Vanadium alloy steel. It has a yield strength of about 70,000 psi and tensile strength of about 100,000 psi. 4340 is an excellent choice for parts that need heat-treated or machined in the as-forged condition. Also, 4340 alloy is a low-carbon steel containing nickel, chromium, copper, and molybdenum as girding agents.

A 4340 alloy stel barl and its strongest feature which is its toughness and hardness, is also known to have good shock and impact resistance as well as abrasion resistance.

Moreover, its good ductility allows it to be easily bent and formed allowing industries to unanimously choose a 4340 alloy steel bar to create parts and components that have to be heavily machined under stressful conditions.
