Product Details
The tensile strength of ST42 Carbon Steel Pipe shall not be less than 42kgf/mm2, which is 420MPa.
ST42 Carbon Steel Pipe is a German standard seamless steel pipe, which is widely used. German standard seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for fluid transportation .
According to different uses, it can be supplied in three categories: a. according to chemical composition and mechanical properties; b. Supply according to mechanical properties; c. Supplied as per hydrostatic test. The steel pipes supplied according to class a and b shall also undergo hydrostatic test if they are used to withstand liquid pressure. 3. Seamless tubes for special purposes include boiler seamless tubes, chemical and electric power seamless tubes, German standard seamless tubes for geology and seamless tubes for petroleum.
The German standard seamless steel pipe has a hollow section, and is widely used as a pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steels such as round steel, steel tubes are light in weight when their bending and torsional strength are the same, so they are a kind of steel with economic section.
German standard seamless steel pipe materials: ST33, ST37, ST37.2, ST35.8, ST35.4, ST35.8, ST35.8, ST42, ST42.2, ST45.8, ST45.8, ST45.4, ST52.4, ST52.3, ST52, etc.

Custom-made irregular-shaped tubes
Irregular-shaped tubes are hollow steel materials with non-standard irregular cross-sections, which are different from ordinary round tubes. We support customized production based on drawings and samples. The cross-section, material, wall thickness, and length can be adjusted according to working conditions to reduce subsequent cutting and welding processes and improve the overall strength and assembly accuracy of the components.
Packing and shipping
Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
