Our steels have been widely applied to many industries and fields, such as the construction industry, shipbuilding industry, pressure vessels and boilers, oil and gas, bridge construction, offshore platforms, stamping cold forming,etc.
In the process of stainless steel forming, cold rolling technology and hot rolling technology are mainly used. Even in cold processing, there are many different ways to do this. The following is a brief introduction to some of the common cold forming methods for stainless steel. (1) Cold Bending Forming
2 THE FORMING POTENTIAL OF STAINLESS STEEL About stainless steels Stainless steels are iron alloys with a mini-mum chromium content of 10.5% (by weight) and a maximum of 1.2% carbon, necessary to ensure the build-up of a self-healing oxide layer – known as the passive layer – which provides the alloy’s corrosion resistance.
Studies on Stainless Steel Warm Forming. Previous studies by Shinagawa and Takuda indicate that warm forming of stainless steel sheet reduces martensite formation when forming at elevated temperatures. 2,3 These researchers performed drawing tests of cylindrical cups made of types 304 and 316 stainless steel. Figure 1 shows the experimental setup used by Takuda.
Cold Forming Stainless Steel. FABRICATION - COLD FORMING. All Columbus Stainless Steels supplied in the annealed condition (No.1, HRA, 2D, 2B or BA) can be cold formed by any of the conventional processes.
COLD FORMING STAINLESS STEEL BAR AND WIRE . 1 Design Versatility of Stainless Steels Probably the most significant characteristic of stain-less steels, from the design viewpoint, is versatility. This unique family of corrosion-resistant metals has few lim-
In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable (inoxidizable), is a steel alloy, with highest percentage contents of iron, chromium, and nickel, with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass.
The mechanical properties for the different tempers of 301 are obtained by cold working and not by heat treating. 301 1/2 Hard (AMS 5518) material has a miniumum tensile strength of 150ksi and is used in the fabrication of parts that require strength and involves moderate drawing or forming.

The following are the designations of cold working tempers as defined by ASTM A 666, Standard Specification for Austenitic Stainless Steel, Sheet, Strip, Plate & Flat Bar. 1/4 Hard, 1/2 Hard, 3/4 Hard, Full Hard. Reheating the cold worked austenitic stainless steel at temperature below 370C (700F) increases the tensile strength.

Abstract. Stainless steel exhibits greater extent of strain hardening than carbon steel, which leads to significant change in mechanical properties (increase in yield strength and decrease in ductility) of the stainless steel material due to the cold forming process.

Thread forming taps are also known as fluteless taps, form taps, roll taps or cold forming taps.They form threads by displacing material without producing chips. Form taps are used on aluminum, brass, copper, lead, stainless steel, carbon steel, cast steel, leaded steel and zinc as well as other mild steels and medium alloys.
With its superior cold working properties, it can be used for severe cold forming operations and exhibits short time tensile and creep strength properties at more Similar in composition to Type 302, Type 316 stainless steel wire has a slightly higher nickel content and 2-2.50% molybdenum giving this alloy better corrosion resistance.
Cold Forming. Alloy C276 nickel alloy plate should be in the annealed condition for cold working. The alloy has a higher work-hardening rate than the austenitic stainless steels which should be taken into consideration. An in-process anneal may be necessary with a high degree of cold working.
Usually we work with stainless steel plate, but occasionally we will use stainless steel squares, flats and bars to fabricate parts, equipment and components for our customers. We focus on heavy duty steel forming and processing projects using stainless steel that is 1/4 inch, 3/8 inch, 1/2, 1 inch, 2 …
The hydraulic shear, rated 3/4” (19 mm) mild steel, will handle 1/2” (12.7 mm) alloy plate. Good shearing practice cuts about 20% of the metal and fractures the remaining 80%. Heavier thickness plate is best cut by abrasive wheels, which produce a smooth, close tolerance surface.
