316 stainless steel pipe stands as a premium representative among austenitic stainless steel pipes. Enhanced with molybdenum (Mo) in its composition, it demonstrates significantly improved corrosion resistance, high-temperature stability, and mechanical properties compared to the base 304 stainless steel pipe. It performs exceptionally well in environments containing chlorine, salt, or highly corrosive media.

304L stainless steel pipe is a quintessential example of ultra-low-carbon austenitic stainless steel pipe, developed by optimizing conventional 304 stainless steel. By reducing carbon content to ≤0.03%, it addresses the susceptibility of 304 steel to intergranular corrosion following welding or high-temperature use, while retaining the superior corrosion resistance, toughness, and machinability characteristic of austenitic stainless steel.

ASTM A179 specifies the technical requirements for seamless cold-drawn low-carbon steel tubes with minimum wall thicknesses, intended for use in tubular heat exchangers, condensers, and similar heat transfer equipment. The standard covers steel tubes with external diameters ranging from 1/8 inch to 3 inches (3.2 millimetres to 76.2 millimetres).

20# carbon steel pipe is a widely used high-quality carbon structural steel pipe within China's national standard (GB/T) system. Its core characteristics lie in its moderate carbon content and balanced comprehensive mechanical properties. It possesses exceptional versatility across petroleum, chemical, mechanical, and construction sectors, serving as the ‘foundational pipe material’ within industrial piping systems.

ASTM A36 carbon steel pipe is manufactured to the ASTM A36 standard established by the American Society for Testing and Materials (ASTM). With its excellent mechanical properties, good machinability and high cost-effectiveness, it has become one of the most widely used carbon steel pipes in global industrial applications.

Q460 carbon steel coils are defined within the Chinese National Standard (GB/T 1591-2018 “Low-Alloy High-Strength Structural Steel”) as high-strength low-alloy carbon steel coils. Their core characteristics are ‘high strength and favourable comprehensive mechanical properties’. They are extensively utilised in industrial applications demanding high load-bearing capacity and weight reduction, serving as a key material for structural lightweighting to replace traditional medium- and low-strength steels (such as Q235 and Q355). and achieving structural lightweighting.
