Q235B square tube
Features
Chemical composition: Q235B is a carbon structural steel with a chemical composition of carbon (C) ≤ 0.22%, manganese (Mn) ≤ 1.4%, silicon (Si) ≤ 0.35%, and phosphorus (P) and other elements also have corresponding content standards.
Mechanical properties: The yield strength is 235MPa, and the tensile strength is between 370-500MPa. Compared with Q355B, its strength is lower, but it has certain toughness and plasticity.
Use
Q235B square tube is mainly used in construction, bridges, ships and other fields, and is also suitable for some structures and components that do not require particularly high strength. For example, it is widely used in the frame structure of some ordinary buildings, the secondary components of small bridges, agricultural machinery and equipment, etc.
Q355B square tube
Features
Good weldability and processing performance: Whether it is welding or cutting, bending and other processing processes, Q355B square tube can maintain good performance stability and reliability, which is convenient for construction and manufacturing.
Excellent corrosion resistance: The low alloy component design makes it have excellent corrosion resistance. It can maintain a long service life and stable performance in highly corrosive environments such as marine engineering and chemical equipment.
Good plasticity and toughness: It is easier and more reliable during the forming and cold bending process, and can be made into parts of various complex shapes.
Environmental protection: The low alloy design reduces the impact on the environment and meets the requirements of modern society for environmental protection and sustainable development.
Uses
Construction industry: Due to its high strength and weldability, it has become an ideal choice for building load-bearing structures. It is used in engineering structures such as high-rise buildings, large factories, bridges, etc. to provide stable and reliable support and protection.
Machinery manufacturing field: It is used to manufacture various parts with large forces, such as chassis and outriggers of heavy machinery such as cranes and excavators.
Other fields: It is also widely used in ships, petrochemicals, electricity, water supply pipelines and other fields.
