Alloy steel pipe & tube

The benefits of alloy steel pipe include its tensile strength, yield strength, fatigue resistance, toughness, and wear resistance.

ASTM A519 grade 4130

ASTM A519 carbon and alloy steel mechanical tubing
A519 Gr.4130 standards applicated in the seamless alloy pipe.

Its performance is much higher than the average of seamless steel tubes, because the steel contains Cr more inside, alloy seamless pipe, its high temperature, low temperature resistance, corrosion resistance is smaller than other seamless.

Especially, it need to do the quenched & tempered and has a high technical requirements. so alloy tube in the petroleum, chemical, electric power, boiler and other industries use more widely.
