Good Mechanical Properties:
High Strength: The yield strength is generally around 235MPa, and the tensile strength can reach 370 - 500MPa. It can bear a certain load and stress and meets the basic requirements for steel strength in fields such as building structures and machinery manufacturing.
Good Toughness: It has good toughness. When subjected to external forces such as impact or vibration, it can absorb energy and is not prone to brittle fracture. This is very important for some structures or equipment that may bear dynamic loads.
Suitable Ductility: It has good ductility and allows for deformation processing to a certain extent, such as bending, stretching, and stamping, which is convenient for manufacturing parts of various shapes and sizes.
Good Welding Performance: The carbon equivalent is relatively low. During the welding process, welding defects such as cracks and pores are not easily generated, and the strength of the welded joint is high, which can ensure the quality and reliability of the welded structure. Therefore, Q235H steel is widely used in engineering structures that require welding, such as buildings, bridges, and pressure vessels.
Superior Machinability:
Easy - to - Cut Machining: The proportion of hardness and toughness of the steel is moderate. During the cutting process, the tool wear is small, and the machining efficiency is high, which can reduce the machining cost.
Good Formability: Whether it is cold working or hot working, it can be relatively easily processed into products of various shapes and sizes. For example, through rolling, forging, squeezing and other processes, different - sized section steel, steel plates, and steel pipes can be produced.
Economical and Practical:
Low Cost: The production process of Q235H steel is relatively simple, and the raw material sources are extensive. Therefore, its price is relatively low and it has a high cost - performance ratio and can meet the needs of large - scale use in many engineering fields.
