Always we will quote you price based on drawings ,or you can tell us the dimension . Then according to your application and quantity ,we will send you quotation soon. The price is differ from different materials .

then we will quote based on What kind of the steel ?The maximum tensile strength of the steel ?The minimum and maximum thickness of the steel ?

According to your application ,we will recommend you the best material and hardness .

Optional Materials :9CrSi , 6CrW2Si , LD , D2 , Cr12MoV , H13 , G1, G2 ,G3 and etc .

Sparkblades has developed some high alloy steel ,like G1 , G2 ,G3 etc . They are new materials developed independently by our company and excellent in high intensity , high hardness , high wear resistance , high toughness and so on . They can be used in both cold and hot shearing ,the life is 2-3 times longer than other blades made of normal materials .

Hardness : If hardness is high , when the blades meet higher tensile strength steel ,it is easy to crack . If the hardness is low , then the wear resistance is not good ,that means work life is shorter .

1. BlankingSelecting material according the customers’ request.
2.ForgingIncreasing the density of the material.
3.TemperingLowering temperature for processing.
4.Finishing machiningMaking the material shaped.
5.InspectionChecking the products if they are the same as the drawing.
6.HardeningIncreasing the hardness of products and the material.
7.AnnealingTo incrase abrasion resistance, need to anneal thermal insulation for long time.
8.Hardening and temperingHardening and tempering the parallel of products for processing.
9.Coarse grindingCoarse grinding the surface of products to be shaped.
10.Accurate grindingSupergrinding to incrase the precision and the parallel of products.
11.TestingRefusing the unqualified products into the market.
12.PackagingDifferent products, different packaging.
Generally, we pack our goods in neutral white papers and cartons. If you have legally registered patent, we can pack the goods in your branded boxes after getting your authorization letters.
