When slitting aluminum coil in Portland, you’ll want high quality results. But equipment failure and irregular upkeep often result in problems — one of the most common of which is a ‘burr’. A ‘burr’ essentially refers to the creation of rough edges that sometimes form on the metal piece during the slitting process. Since a […]

  The 400 series stainless steel was the first-ever version of stainless steel. It consisted of martensitic and ferritic products, with chromium being the only alloying element. This made the series reasonably priced compared to many austenitic grades. They are magnetic, more resistant to chloride, and can also be strengthened with heat treatment. Amongst its […]

  Grade 304 stainless steel can be used for a variety of purposes. It’s one of the most widely used stainless steel products, and it’s also available in multiple forms and finishes. It’s ideal for forming and welding projects due to the fact that it offers a balanced, austenitic structure. At National Kiwkmetal Service, we […]

  Stainless steel doesn’t just refer to a single product, but a variety of them — including grade 301. What makes stainless steel different is its chromium content, which is usually combined with nickel for better corrosion resistance and greater ductility. The 301 stainless steel strips and coils have been the flagship products of NKS for […]

  An Introduction to Type 301 Stainless Steel and Stainless Steel Slitting Services in Cleveland, Ohio Type 301 is an austenitic stainless steel that’s more magnetic than other standard grades when cold worked. However, it continues to be nonmagnetic in the annealed state. In the annealed condition, the grade offers an increased level of stretch […]

  Type 439 stainless steel is a ferritic, titanium stabilized, 18% chromium alloy material with corrosion resistance that is more or less equivalent to grades 304 and 304L. This type is commonly used in applications such as exhaust system components or tubular manifolds, where Types 304 and 304L and Type 430 may also be considered […]

  Are you seeking a cost-effective alternative to the 200 and 300 series stainless steel grades that can handle even the harshest temperatures? Then you should consider 409 stainless steel. Grade 409 stainless steel is a general-purpose, titanium-stabilized, ferritic alloy that offers excellent chemical, mechanical, and physical properties. It is commonly said to be the […]

   Type 304 and 304L are commonly used austenitic stainless steel. These are relatively low cost, extremely formidable, and resistant to atmospheric corrosion. Both types have similar chemical and mechanical properties, but the main difference lies in their carbon content. You might be wondering, what makes these two stainless steels so versatile, and what are […]

  Grade 430 stainless steel is by far the most sought-after non-hardenable, straight chromium type of stainless steel. It is a general-purpose alloy that falls under the ferritic stainless steel class. Type 430 offers an excellent combination of (mild) atmospheric corrosion resistance and formability, with many useful mechanical properties. This grade of stainless steel can […]
