High strength and hardness: steel has a high strength and hardness, suitable for manufacturing building structures, heavy machinery, etc.
Good processing performance: steel has good processing performance, can be smoothly formed, welding, cutting and other processing technology.
Corrosion resistance: Some special steels can have strong corrosion resistance and are suitable for use in special environments.
Environmental protection: By recycling scrap steel, you can reduce the waste of resources and environmental pollution.
Rich resources: Iron and steel material resources are rich, the content of iron in the crust is about 4.2%, easy to obtain.
High recovery rate: the recovery rate of steel materials can reach more than 90%, which is conducive to the recycling of resources.
Stable quality, low price: steel material is a relatively mature material, rich production management experience, the price is relatively low.
Good comprehensive mechanical properties: steel materials have a wide range of amplitude modulation of organizational properties, a wide range of strength, good plasticity and toughness, and are easy to process into arbitrary shapes.
Good toughness: While maintaining a certain strength, steel materials have good toughness and can withstand large deformation and dynamic load10.
Recyclable: Steel materials can be recycled and reused after scrap, reducing the demand for new resources and environmental pollution.
These characteristics make steel an indispensable material in many industrial fields, especially in construction and machine building.
