Sheet metal is metal formed by an industrial process into thin, flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from the metal sheet. Plate and sheet are words used to describe the classification of metal depending on its thickness. While sheet metal is less than 3 mm thick, plate metal is obviously thicker than 3 mm. Steel Plate is used in heavy-duty applications such as those found in the aerospace, military and transportation product manufacturing. Aluminium plate, machined to shape, forms the skins of jets and spacecraft fuel tanks, etc. It is used for storage tanks in many industries, in part because some aluminium alloys become tougher at supercold temperatures. This property is especially useful in holding cryogenic (very-low-temperature) materials.

Stainless Steel Plate is also used to manufacture structural sections for railcars and ships, as well as armour for military vehicles. In transportation, the metal sheets are used to manufacture panels for automobile bodies and tractor trailers. In building and construction, it is formed into products including siding, gutters, roofing, awnings and carports. Stainless Steel Sheet Plates are further categorised in following forms:

Stainless Steel Sheet: If a piece of metal has been rolled out to a thickness greater than that of a foil, but is still less than 6mm it is called sheet. SS 304H Sheet and Stainless Steel Sheet is in ready stock with Siddhagiri Metals and Tubes.

Stainless Steel Shim Sheet: A shim is thin and often tapered or wedged piece of metal. Shim Sheet is used to fill small gaps or spaces between objects. Sheet Shims are typically used in order to support, adjust for better fit, or provide a level surface. SS 304H Shim Sheet and Stainless Steel Shim Sheet is in ready stock with Siddhagiri Metals and Tubes.

Stainless Steel Rolled Sheet Coil: Sheet Coils are flat products wound into rolls and having a rectangular cross-section, the width of which is much larger than the thickness. Hot Rolled Sheet Coil is produced from semifinished products (slabs or billets), which are reduced to certain thicknesses by rolling and annealing and wound into a roll. Cold Rolled Sheet Coil is produced by removing rust from a hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll. Cold-rolled steel Coil is a more highly finished product and has a smoother surface, greater dimensional accuracy (thickness, width, length) and greater strength. SS 304H Rolled Sheet Coil and Stainless Steel Rolled Sheet Coil is in ready stock with Siddhagiri Metals and Tubes.

Stainless Steel Rolled Sheet Strips: Sheet Strip is a flat product which, immediately after the final rolling pass or after pickling or continuous annealing is wound into laps so as to form a coil. Strip of Sheet as rolled has slightly convex edges, but it may also be supplied with sheared edges or slit from a wider strip. Wide Strip is a strip of a width 600 mm or over, Whereas, Narrow Strip is a strip of a width less than 600 mm. SS 304H Rolled Sheet Strips and Stainless Steel Rolled Sheet Strips is in ready stock with Siddhagiri Metals and Tubes.

Stainless Steel Plate: Once the metal is more than 6mm thick it is known as plate metal. This type of material is used in circumstances whereby strength and durability are of the utmost importance. SS 304H Plate and Stainless Steel Plate is in ready stock with Siddhagiri Metals and Tubes.

Stainless Steel Diamond Plate: Diamond plate, also known as a chequered plate, thread plate and floor plate, is a type of metal designed with a regular pattern of raised diamonds or lines on one side, with the reverse side being featureless. Diamond plate is usually stainless steel or alloy. SS 304H Diamond Plate and Stainless Steel Diamond Plate is in ready stock with Siddhagiri Metals and Tubes.

Properties of AISI 304H Stainless Steel

304H SS Cold Forming

304H Stainless Steel is readily formed and fabricated through a full range of cold working operations. It can be used in heading, drawing, bending, and upsetting. Any cold working operations will increase the strength and hardness of the material, and may leave it slightly magnetic.

304H SS Hot Forming

304H Stainless Steel can be forged in the 1700-2200°F range. For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.

304H SS Machining

304H Stainless Steel is a tough austenitic stainless steel subject to work hardening during deformation and, unless modified for improved machining response, is resistant to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling, and powerful, rigid equipment.

304H SS Welding

304H Stainless Steel is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308H/ER308H filler metals should be used with Type 304/304H steel. After welding Type 304H it may be necessary to fully anneal to restore the corrosion resistance lost by sensitization to intergranular corrosion when chromium carbides were precipitated in the grain boundaries in the weld heat-affected zone.

304H SS Heat Treatment

Annealing: Type 304H should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type 304H cannot be hardened by heat treatment. However, Type 304H can be hardened by cold working.
