Description

Alloy pipe is a kind of seamless steel pipe, its performance is much higher than that of general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance performance is much better than other Steel pipe, so the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.
Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels.
Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium.

Scope
ASTM A333 covers nominal (average) wall Seamless and Welded carbon and Alloy Steel pipe intended for use at low temperatures. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
Material & Manufacture
The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.

Heat Treatment Requirements
All Seamless and Welded pipe shall be treated to control their micro structure by the following methods: Normalizing per A 333/A 333M-05 section 4.2.1.1; section 4.2.1.2 or section 4.2.1.3 Quenched and Tempered per A 333/A 333M - 05 section 4.2.2.1 Double Normalized and Tempered per A 333/A 333M - 05 section 4.2.2.2
