BBN STEEL hardox 450 steel properties new technology

A small amount of Nb is sufficient to obtain excellent comprehensive properties of Hardox 450 steel properties etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

RAEX400 steel is a hardened wear-resistant steel material with an average grade of 400HBW and a Brinell hardness. The microstructure of this wear-resistant steel is a martensite structure, which can ensure the high hardness and tensile hardness of the steel plate. The hardness of RAEX400 is 2.5 times that of S355 structural steel, Hardox 450 steel properties. Despite its high hardness and high strength, RAEX400 steel can be formed by free bending or hemming, and has good weldability.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for Hardox 450 steel properties various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several Hardox 450 steel properties after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

Welded steel pipe refers to the steel pipe with a joint on the surface which is welded after the steel strip or steel plate is bent and deformed into circular, square and other expected shapes. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, Hardox 450 steel properties, etc. According to the weld shape, it can be divided into straight welded pipe and spiral welded pipe. Electric welded steel pipes are mainly used in oil drilling and production, machinery manufacturing, etc.; furnace welded pipes can be used as water gas pipes, large-diameter straight seam welded pipes for high-pressure oil-gas transmission, etc.; spiral welded pipes are used for oil-gas transmission, pipe piles, piers, etc. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe.
