SST machinery provides 3000PSI flange connector, 6000PSI flange connector, as well as 9000PSI flange connector, the regular size is from 1/2” to 2”. The material of hydraulic flange connector is carbon steel Q235, the surface treatment we applied is Cr6free white galvanization.
Our regular packaging of hydraulic flange connector is mass packaging, we will use standard export packaging, that is plastic bag+boxes+plywood pallet to protect our goods, we also can proceed custom packaging, such as individual packaging for 10pcs or 20pcs in a small bag, or special boxes, just the packaing cost is higher, so if it is possible, we recommend our general export mass packaging, which is already enough to achieve good sea worthy delivery.
Zinc is soluble in acid and alkali, so it is called amphoteric metal. For steel, zinc coating is a positive coating, which is mainly used to prevent corrosion of steel. The protective and decorative properties of zinc coating can be significantly improved after passivation treatment, dyeing or coating with light protectant. Such as screws, guide rails, as well as flange connector.
SST machinery is one of the most professional hydraulic parts manufacturers and suppliers in China, We not only produce a comprehensive range of hydraulic fittings, adapters, couplings, engineered components for all types of industrial environments, but also provide professional solutions for various hydraulic connections in many fields like military, marine, automotive, power generation, construction, machinery, mining,etc...
STAINLESS STEEL COMPOSITION
The American Iron and Steel Institute has conducted in-depth studies resulting in a simplified list of stainless steel composition types. This list is known as “standard types.” These types were selected on the basis of metallurgical judgment after considering many factors such as the counsel of engineering and specification writing bodies, as well as the needs of the armed services. This method of standardization has led to identification by types according to several groups, using a simple system of numbers and sometimes letters. In a 3 digit number, the first digit indicates the series or group, and the last two digits indicate the type. Modifications of types are indicated by suffix letters. The series designations identify the following groups:
Stainless Steel Composition and Major Characteristics
