Stainless steel cladding steel plate and manufacturing method thereof

Abstract

The invention discloses a stainless steel cladding steel plate which comprises an outer stainless steel layer (1) and an inner steel core layer (2); the outer stainless steel layer (1) wraps the periphery of the inner steel core layer (2), the outer stainless steel layer (1) and the inner steel core layer (2) are formed through hot rolling bonding, and metallurgical bonding is formed between the outer stainless steel layer (1) and the inner steel core layer (2). The outer stainless steel layer (1) comprises a stainless steel upper layer (101), a stainless steel lower layer (102) and a stainless steel side wall layer (103), and the ratio of the thickness of the stainless steel upper layer (101) to the thickness of the inner steel core layer (2) is 1:(1.5-50). The corrosion resistance of thestainless steel cladding steel plate is greatly improved, except the joint parts of the two ends of the stainless steel cladding steel plate and other components, the stainless steel cladding steel plate is coated with stainless steel in the upper, lower, front and rear directions, so that the internal inner steel core layer is strictly protected, and the inner steel core layer is not corroded due to contact with the outside or a third medium. The invention further discloses a manufacturing method of the stainless steel cladding steel plate.

Description

technical field [0001] The invention relates to the technical field of metal materials and metallurgical steel rolling, in particular to a stainless steel clad steel plate and a manufacturing method of the stainless steel clad steel plate. Background technique [0002] Reinforcing bars and steel plates are important raw materials for reinforced concrete and infrastructure construction, and are widely used in construction fields in all walks of life. Traditional steel bars and steel plates are produced from carbon steel materials, but carbon steel has the shortcomings of easy oxidation and corrosion. Especially in the waterside and underwater concrete such as coastal areas and rivers, the corrosion of the steel bars in the concrete by chloride salts is intensified with the passage of time. service life and safety. [0003] At present, as an improved clad steel plate, the upper surface, the lower surface or the upper and lower surfaces of the ordinary carbon steel are mainly ...

AI Technical Summary

Problems solved by technology

Stainless steel bar / stainless steel plate has excellent corrosion resistance, but its yield strength is relatively low

Ordinary carbon steel has high strength, but at the same time, with the improvement of strength and other national performance indicators, its elongation and other toughness indicators will decrease, which will affect the safety of buildings
