High Quality SUS 304 / 316 Stainless Steel slotted set Screws

Description:

The main standard parts on the market are carbon steel, stainless steel and copper.

A carbon steel.We use the carbon content of carbon steel material to distinguish low carbon steel, medium carbon steel and high carbon steel and alloy steel.

1 low carbon steel C%≤0.25% domestic commonly known as A3 steel.It is basically known as 1008,1015,1018,1022, etc.Mainly used for grade 4.8 bolts, grade 4 nuts, small screws and other products without hardness requirements.(note: 1022 material is mainly used for drilling tail nail.)

2 medium carbon steel 0.25%

3 high carbon steel C%>0.45%.It's not used on the market

4 alloy steel: adding alloying elements to ordinary carbon steel to increase some special properties of steel, such as 35, 40 cr-mo, SCM435, 10B38.Aromatic screw mainly USES SCM435 chromium molybdenum alloy steel, the main components are C, Si, Mn, P, S, Cr, Mo.

Two stainless steel.Performance levels: 45,50,60,70,80

1 mainly austenite (18%Cr, 8%Ni) good heat resistance, corrosion resistance, good weldability.A1, A2, A4

2 martensite, 13%Cr poor corrosion resistance, high strength, good wear resistance.C1, C2, C4 ferritic stainless steel.18%Cr had better upsetting and corrosion resistance than martensite.The imported materials on the market are mainly Japanese.The main grades are SUS302, SUS304 and SUS316.

Three copper.Common material is brass...Zinc-copper alloy.On the market, H62, H65, H68 copper do standard parts.
