Product Inquiry

Product Introduction:

　　Product features: A small amount of Nb, Ti, V and other alloy elements are added in low carbon steel, so that it can form carbide and nitride with carbon , nitrogen and other elements, and precipitation in the ferrite matrix, so as to improve the strength of steel; Through precipitation strengthening and fine grain strengthening, higher strength grades can be obtained while the content of alloying elements is reduced.

Performance characteristics: good formability and high strength, the product has a certain aging performance.

Main application: used in structure parts such as car seats and beam etc

Application Case:

Supply Standard:

Can supply product according to the requirements of European standard and other international standards, or according to the standards or requirements of users.

Performance list of hot dip galvanized low alloy high strength steel series

Grade	Yield strength Mpa	Tensile strength Mpa	Elongation after fracture A_80mm(％)
H260LAD+Z	260–330	350–430	≥26
H300LAD+Z	300–380	380–480	≥23

H380LAD+Z	380 to 480	440–560	≥ 19
H420LAD+Z	420 to 520	470–590	≥ 17

a: If there is yield point, take lower yield strength Rel.
b: The sample is P6 sample in GB/T 228.1-2010, and the direction of the sample is transverse.
c: For products with thickness t≤0.5mm and 0.5mm < T ≤0.7mm, the elongation can be reduced by 4% and 2%, respectively.
