- Alloy Steel Welded Pipes: Crafted for durability and resilience, Alloy Steel Welded Pipes cater to applications preferring a welded construction.
Apart from chrome, molybdenum, and vanadium, Alloy Steel pipes can be enriched with carbon elements like cobalt, nickel, niobium, titanium, tungsten, and zirconium. These additions contribute to specific alloying effects, each chosen for its unique benefits.
In the piping industry, every steel pipe is essentially an alloy pipe, whether it’s a carbon alloy pipe or a chrome moly alloy steel pipe. The term ‘alloy steel pipe’ is used when the content of Manganese surpasses 1.65%, Silicon exceeds 0.6%, and copper is elevated beyond 0.6%.
Alloy Steel pipes undergo essential heat treatment processes to fine-tune mechanical properties in alignment with specific alloying elements. Several heat treatment methods play a pivotal role in shaping the performance of Alloy Steel pipes:
- Normalize Quench and Tempering: This method involves normalizing the steel, followed by quenching and tempering. It aims to strike a balance between hardness and toughness, enhancing the overall mechanical attributes of the alloy.
- Quench and Tempering: In this process, Alloy Steel pipes are quenched and subsequently tempered to optimize hardness and strength. This treatment imparts superior resistance to wear and fatigue, making the pipes suitable for demanding applications.
- Normalizing & Hardening: Normalizing precedes hardening, where the steel is heated to a specific temperature and then cooled in the air. The subsequent hardening step further enhances the hardness and strength of Alloy Steel pipes, ensuring robust and durable performance.
