The 304 stainless steel sheet has a #4 brushed finish, has been annealed, meets American Society for Testing and Materials International ASTM A240 and American Society of Mechanical Engineers ASME SA240 specifications, and has a standard tolerance. The 304 stainless steel grade is a general-purpose material that combines corrosion resistance, weldability, and formability, making it the most commonly used grade of stainless steel. An austenitic stainless steel that is one of the 18-8 grades, 304 can be cold worked to increase its hardness and strength while maintaining most of its formability. The material is typically nonmagentic but may become slightly magnetic when cold worked. The #4 brushed finish has a moderately reflective appearance with fine parallel polishing lines. The material has been annealed, a method of heating and cooling metal to modify its properties, such as increasing its formability and toughness or decreasing its strength, after it has been shaped.
Stainless steel is an iron alloy with resistance to staining and rusting in many environments where steel would typically degrade. The chemical composition of each grade creates a grain structure that falls into one of five classes: austenitic, duplex, ferritic, martensitic, and precipitation hardening. The austenitic class contains the most formable, weldable, and corrosion-resistant stainless steel grades, but they cannot be heat treated. The duplex class offers high resistance to pitting and chloride stress corrosion cracking. Duplex grades are heat treatable and roughly twice as strong as austenitic grades. The ferritic class contains moderately formable and corrosion-resistant grades compared to other stainless steel classes, but they cannot be heat treated. The martensitic class includes some of the hardest and strongest stainless steel grades that also offer mild corrosion resistance, high hardness, and good formability. Martensitic grades can be heat treated. The precipitation-hardening (PH) class can be heat treated after fabrication to achieve some of the highest hardness ratings in stainless steel.
Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded. Magnetism characterizes how much the material is repelled by or attracted to a magnet.

More importantly, I needed these two pieces to lay end-to-end to form the backsplash. What I discovered when I unwrapped them was that one was brushed length-wise, and the other was brushed 90 degrees (width-wise?) to that. So... it looks strange with the change in brush direction. When ordering this material, there isn't a way to specify which way the brush grain should run, unfortunately. So I got unlucky, getting two different grain patterns. I guess I could have ordered 3, then I'd be guaranteed a pair that matched, but obviously that is a lot of extra money. Amazon - add a feature allowing the buyer to specify the grain for the pieces ordered!
Other than that, this is excellent material and even with the grain problem, the kitchen looks great with it. When I get some time, I'll use a random orbit sander with steel wool or such to randomize both sheets, but I would have been happier with matching grain!
The finish looks great though.
One corner was damaged in shipment, it doesn't seem to get enough protection during transit

It's a piece of stainless steel. I should've done my homework first because it's not magnetic so therefore useless to me. Not their fault. Read morePublished 1 month ago by Steven StClair
