Our Wires Classified by Grades

Grades available: 302HQ, 304 Series, 304J3, XM7, 305, ER308, ER309, Y309, 316, 316L, 410, 410C, 430, 204Cu
(selected grades introduced below)
Types/Grades Group Family Description
Type 302 series  Austenic Type 302 series is the most widely used heat resisting and chromium nickel stainless steel.
Type 304 series Austenic Type 304 series is chromium nickel stainless steel. Type 304 steel is commonly used in sanitary applications.
Type 316 Austenic Type 316 has higher resistance to corrosion than other steel types. It is usually specified for industrial equipments that handle the corrosive process chemicals used to produce photographic chemicals, bleaches, and rubber.
Type 410 series Martensitic Type 410 series is always magnetic, and it can be hardened by thermal treatment to a wide range of mechanical properties. Type 410 can be annealed soft for cold drawing and forming. It is the basic type of Martensitic family.
Type 430  Martensitic Type 430 has excellent resistance to atmospheric corrosion and good ductility. Its scaling resistance is higher than 302.

Our Wires Classified by Surface Finish

Regardless of the intentional use, surface finish is an important aspect in stainless steel wire specification. When the appearance of the applications is important, surface finish is a design element and must be clearly specified. In non-decorative applications, the surface finish may have implications for maintenance and must be carefully chosen.

Bright Finish

The surface of bright finish wire is bright, smooth and beautiful. It is done by the processing of annealing. It has excellent flexibility and softness.

Oxalate Coated

The oxalate coated on the wire is a lubricant for subsequent processing. Oxalate is applied in a dipping and baking tank.

PC Coated

PC coated wire has water soluble coatings applied on surface by dipping and baking. The coatings act as a lubricant for later processing.

Our Wires Classified by Condition

The end usage of the wire dictates the preferred hardness. Hardness of stainless steel wire varies from very soft to very hard (spring temper), it can be accomplished with cold working to increase the strength. A combination of cold working and annealing can achieve a specific strength (e.g., a bendable tie wire would be annealed to make it softer).

Soft Annealed Wire

Soft annealed wire are drawn to final size and heated to remove the effects of cold working. It has the softest condition for extreme cold heading.

Skin Passed Wire

Skin passed wire also refers to half-hard wire or lightly-drawn wire. It's processed to produce a strength in the midway between soft wire and hard wire.

Hard Wire

Hard wire is also know as hard-drawn wire. These wires have been cold drawn to final size to approach the maximum attainable strength.

Our Products and Their Designations

Stainless steel are usually designated by the 3-Digit System and the U.N.S. Number System. Other systems are also used around the world. Below is a chart of selected steel types and their designated numbers under different systems. Our customers are advised to use these numbers when inquiring with us.

Our End Products with Various Hardness and Finishes

Annealed and Pickled

After drawing to a speficied size, it's annealed and pickled. Appeared in gray and has matt finish.

Bright Drawn

Bright drawn wire has bright surface that obtained by cold drawing. It's cleaned to have brilliant surface.

Cold Drawn

Cold drawn wire can be cleaned upon request. It has semi-matt surface. It has been lightly drawn in soap.

Temper Drawn

Temper drawn wire can have either cold drawn or bright drawn finish. It is drawn in oil or soap to achieve certain tensile strength.
