Introduction of common steel cold and hot rolling
Wire: 5.5-40 mm in diameter, coiled, all hot-rolled. After being cold drawn, it is a cold drawn material.Round steel: except for the precision-sized bright material, it is generally hot-rolled, and there are also forged materials (with forging marks on th
What are the differences between hot rolled steel plates and cold rolled steel plates?
The hot rolled steel plates have low hardness, easy processing and good ductility. The cold rolled steel plates have high hardness and are relatively difficult to process, but they are not easy to deform and have high strength.Hot rolled steel plates have
Precautions for steel storage
The site or warehouse for storing steel should be in a clean place with unobstructed drainage, far away from factories and mines that produce harmful gases or dust.Do not stack with acid, alkali, salt, cement and other materials that are corrosive to stee
Introduction of galvanized steel pipe
Galvanized steel pipe is a steel pipe with a hot-dip or electro-galvanized coating on the surface. Galvanizing can improve the corrosion resistance of steel pipes and prolong its service life. Galvanized steel pipe has a wide range of uses. In addition to
The difference between galvanized steel pipe and ordinary steel pipe
Ordinary steel pipes have worse corrosion resistance than galvanized steel pipes. Galvanizing refers to the galvanizing of the surface of the steel pipe. It can be a welded tube or a seamless tube. Seamless refers to the manufacturing process of steel pip
What are the types of steel
There are many types of steel, which can generally be divided into four categories: section steel, plate, tube and wire.1. Section steelThere are many types of section steel, which is a solid long steel with a certain cross-sectional shape and size. Accor
Steel production method
Most of the steel processing is through pressure processing, so that the processed steel produces plastic deformation. According to the different processing temperature of steel, it can be divided into two types: cold processing and hot processing. The ma
Introduction of round steel tube
Round steel tube is a steel material that is open at both ends and has a hollow and concentric cross-section, and its length is larger than that of the periphery. The size of the round steel tube is expressed by the external dimensions (such as the outer
What is high quality structural steel
High quality structural steel must ensure chemical composition and mechanical properties at the same time. The grade is the ten thousand fraction (ωс**10000) that uses two digits to indicate the mass fraction of average carbon in the steel. For
What are the chemical performance indicators of steel?
The performance indicators of steel are generally divided into mechanical properties, chemical properties and process properties. Among them, the chemical properties of steel refer to the resistance of the steel to chemical or electrochemical reactions wh
How to distinguish weather resistant steel plate and ordinary steel plate?
When purchasing weather resistant steel plates and ordinary steel plates, what should be paid attention to, and what methods are there to distinguish the differences between weather resistant steel plates and ordinary steel plates?1. The small rust spots
Four characteristics of weather resistant steel after rusting
Weather resistant steel is a kind of corrosion-resistant steel. The more rust the better, what are the characteristics of weather resistant steel after it rusts?First, the photosensitive composition is stable, and the color thickness is uniform. At an out
Why should weather resistant steel landscape surface be treated with rust
Weather resistant steel landscape is strictly a kind of corrosive steel plate. In recent years, corroded steel plate has been mainly used to manufacture large-scale machinery and equipment, and is widely used in field steel such as containers, power plant
What are the advantages and disadvantages of high carbon steel
After proper heat treatment or cold drawing hardening, high carbon steel has high strength and hardness, high elastic limit and fatigue limit, and the cutting performance is acceptable, but the welding performance and cold plastic deformation ability are
Comparison of carbon steel and stainless steel
The nature of carbon steel and stainless steel is completely different. Building materials manufactured and produced by carbon steel and stainless steel will also have great differences in service performance and service life. So which carbon steel or sta
