Quick Connector Brass Hexagonal Hose

Galvanized sheet: the cold-rolled sheet is coated with a zinc layer, commonly known as galvanized sheet. The galvanized sheet includes SECC, SGCC, etc., and the galvanized sheet is rust-resistant and corrosion-resistant. The price is relatively high. The general board thickness is 0.4~3.2mm. Its characteristics are superior in paintability, good in fingerprint resistance, good in corrosion resistance, and maintain the workability of cold-rolled sheets. Generally, the thickness of 0.80mm SGCC material is commonly used for chassis and lower cover. The hardness is medium, slightly higher than aluminum and softer than stainless steel. The SGCC material is relatively hard, and the tensile properties are not very good. If this material is used for stretching, the concave and convex molds must be polished very brightly, or they will easily crack, dark cracks, etc. Stainless steel: It can be used to produce various sizes of shrapnel and appearance parts, such as: the shrapnel inserted in the back of the desktop computer case is made of stainless steel and then produced by stamping dies. Stainless steel materials are relatively hard, and sometimes the mold maintenance can not find the gasket, you can use stainless steel materials as an emergency, the punches and knife edges of the stainless steel mold need frequent maintenance to ensure the smooth production of the mold. Otherwise, it is often necessary to repair the mold. Ha ha. Generally, the gasket needs to be spot welded to point the gasket on the part, otherwise it will be more troublesome when it is dropped when the mold is removed next time. Some factories do not allow the use of gaskets. At this time, you can use welding to burn them, and then use a grinder to grind out the required size. Commonly used stainless steel materials are SUS301, SUS304 and so on. SUS200 series (including 201, 202, etc.) SUS300 series (including 301, 304, 310S, 321, 316L, etc.) and SUS400 series (including 409, 410, 420J1, 420J2, 430, 436L, 444, etc.)
