It is easy to cast and weld, which is conducive to manufacturing parts of various shapes and processing and assembly. It also has good plasticity, which is convenient for cutting, bending, stamping and other processes. It can withstand various harsh climate and environmental conditions and has certain corrosion resistance.
Q355B is a low-alloy high-strength structural steel with a tensile strength of 470-630MPa, a yield strength of 280-420MPa, and an elongation of 21-29%. This makes it have better strength and stability under heavy loads and complex working conditions, and can show good plastic deformation ability when subjected to external forces, absorb more energy, and protect the structure from damage.
Q235B is a carbon structural steel with a chemical composition of carbon (C) ≤ 0.22%, manganese (Mn) ≤ 1.4%, silicon (Si) ≤ 0.35%, etc. Q355B is a low alloy steel, and the implementation standards vary depending on the material.
It has excellent castability and weldability, is easy to cast and weld, and is conducive to the manufacture of parts of various shapes and processing and assembly. It also has good plasticity and is easy to cut, bend, stamp and other processes. Due to its low carbon content, the welding process window is wide and it is suitable for most conventional welding methods, such as manual arc welding, gas shielded welding, etc. It is also easy to perform deformation processing such as cold bending and stamping, and is suitable for making special-shaped components.
A333 Grade 6 Seamless Steel Pipe is known for its outstanding performance in cryogenic environments. This steel grade is specially designed to maintain its mechanical properties and toughness even at temperatures as low as -50°C (-58°F). This outstanding characteristic is achieved through carefully controlled chemical composition and manufacturing processes.
API 5L Gr.B steel pipe is a common pipeline steel pipe. API 5L Gr.B steel pipe is usually made of carbon steel and has good weldability and processability.
