Stainless Steel Pipe Types – Based on Alloy Grades
The chemical composition of steel overall has a great influence on end-products mechanical properties and application areas. So, it is no surprise that they can be classified in terms of their chemical compositions. However, while trying to find out the grade of a specific stainless steel pipe, various types of nomenclatures can be encountered. The most used standards when designating steel pipes are DIN (German), EN, and ASTM grades. One can consult a cross-reference table to find equivalent grades. The table below gives a useful overview of these different standards.
DIN Grades EN Grades ASTM Grades
1.4541 X6CrNiTi18-10 A 312 Grade TP321
1.4571 X6CrNiMoTi17-12-2 A 312 Grade TP316Ti
1.4301 X5CrNi18-10 A 312 Grade TP304

Different Types Based on ASTM Specifications
It is a classic saying that industry and standards are closely tied. The manufacturing and testing results may differ due to differences in various organization standards for a wide variety of application ranges. The buyer must first grasp the fundamentals of various industrial specifications for their projects, before actually doing the purchasing operations. It is also an accurate saying for stainless steel pipes.
ASTM is an abbreviation for the American Society for Testing and Materials. ASTM International provides service standards and industrial materials for a wide range of industries. This organization has currently served 12000+ standards that are utilized in businesses all around the world. Stainless steel pipes and fittings are subject to over 100 standards. Unlike other standard bodies, ASTM includes almost all types of pipes. For example, as American pipe items, the entire spectrum of pipe is offered.
