We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
With a **minimum tensile strength of around 760 MPa** and impressive **ductility**, Grade 2HM screws are perfect for use in **sour gas**, **low-temperature**, and **high-pressure** settings. They come in various sizes and configurations, including **hex head**, **socket head**, and **custom designs**, catering to both **metric and imperial systems**.
Alloy Steel Gr 2HM Screws are extensively applied in high-temperature and high-pressure conditions because of their higher strength and durability. They are used in oil & gas, petrochemical, power generation, construction, and heavy machinery sectors, where long-lasting and secure fastening is required. Flange connections, pressure vessels, pipeline assemblies, and structural frameworks are some of the common applications. Their heat-treated material provides greater resistance to stress and corrosion, which makes them suitable for harsh environments that need high performance and reliability.
