GRADE 201

201 alloy is a high performance austenitic stainless steel formulated to have a lower and more stable cost due to the substitution of manganese for a portion of the nickel used in 300 series stainless steels such as Type 304. In addition, the chemical composition of alloy 201 provides higher annealed mechanical properties than type 304 which can result in an additional benefit of weight reduction. The 201 tensile strength is about 10% higher than Type 304 which may allow for thinner gauges and therefore less material. However, due to the lower Chromium and Nickel content, Type 201 stainless may not have the same corrosion resistance as Type 304.

TYPICAL APPLICATIONS

Commercial and residential food service applications, architectural end uses such as handrails and support frame work, washing machines, hose clamps, sinks, containers and structural components of truck trailers and railcars.

GRADE 304/304L

The most widely used of the austenitic grades, 304 offers good corrosion resistance to many chemicals and industrial atmospheres. Generally considered non-magnetic, it can become slightly magnetic when cold-worked. 304 is non-hardenable by heat treatment. In 304L, the carbon content has been lowered to .03% max. for corrosion resistance at heat affected zones from welding.

TYPICAL APPLICATIONS

Architectural trim, beer barrels, cryogenic vessels, dairy equipment, and a wide variety of most food applications.

ALRO'S 6-AxIS TUBE LASERS ARE ThE ONE STEp SOLUTION !!!

Increase Your ProfIts BY elImInatIng these costlY and tIme consumIng stePs WIth laser technologY SAW · FIXTURE · MILL · DRILL · PUNCH · BEND · WELD · ASSEMBLY

Send us your parts file in one of the following file extensions: .par (SolidEdge® files) 3d .iges, .sldprt (SolidWorks® part files) .dxf and .dwg (Autocad® files) .ipt (Inventor® file) In addition we can convert UG files, ProE, Step, and many more via SolidEdge.

Parts produced with Alro's one step laser technology.

Laser cutting slots and tabs eliminate the need for clumsy clamping. Notches can be cut to the desired angle for precision forming. Laser cuts are smooth, practically eliminating the need for grinding and deburring.

Your parts can be produced from any structural shape including angle iron and beams.

After laser cutting, most parts are ready for assembly.

Holes are cut to the desired diameter eliminating the need for drilling or punching with tapping also available.
