Sandmeyer Steel Company manufactures products from stainless steel plate, which is an alloy that contains at least 10.5% chromium. The addition of chromium helps stainless steel plate resist both corrosion and oxidation while varying the levels of chromium and adding nickel alter the mechanical and performance properties. Sandmeyer Steel Company offers a variety of grades of stainless steel plate including 300 series austenitic, martensitic, precipitation hardening, and duplex stainless steel. Grades are selected for the ability to meet a client’s specific needs, whether for resistance to heat, stress cracking, corrosion, pitting, crevice corrosion, and more.
Austenitic Stainless Steel Plate
In austenitic stainless steel plate the addition of nickel alters the crystal structure, which enhances resistance to corrosion. Non-magnetic and not hardenable by heat treatment, austenitic stainless steel plate contains about 18% chromium and 8% nickel. Comprising the most important group of stainless steels due to its ease of fabrication as well as its corrosion and heat resistance, the austenitic grades account for approximately 70% of the stainless steels used today.
Duplex Stainless Steel Plate
The microstructure of Lean Duplex, Duplex and Super Duplex stainless steel plate combines austenite and ferrite in equal amounts, while the material itself is characterized by higher chromium and lower nickel levels than the austenitic grades. Lean Duplex, Duplex and Super Duplex stainless steel plate is stronger than the austenitic grades and provides better resistance to crevice corrosion, chloride stress corrosion cracking, and pitting.
Martensitic Stainless Steel Plate
Containing higher levels of carbon (approximately 0.1% to 1.2%), martensitic stainless steel plate contains 12% to 18% chromium. This composition makes martensitic stainless steel magnetic as well as less resistant to corrosion and oxidation; however, all martensitic grades can undergo heat treatment to attain high strength and good ductility as well as high levels of hardenability. When hardened and stress relieved, this type achieves its highest levels of corrosion resistance.
Stainless Steel Plates by Industry
and Application
Many industries utilize stainless steel plate which
is fabricated to achieve certain mechanical properties
to meet specific performance requirements. Our stainless
steel products are used in industries that include food
processing, wastewater and hazardous waste management,
brewing and beverage bottling, energy management, pulp
and paper, pharmaceuticals, and many more. The durability,
corrosion resistance, and varying mechanical properties
of our plates help achieve the highest standards of
performance regardless of the requirements of the industry
or the stresses applied to the plate. Additionally,
Sandmeyer Steel Company provides value added processes
and can manufacture nearly any desired shape. From our
specialty “Machincut” process to plasma
and abrasive water jet cutting, milling, polishing,
and flattening, we produce and deliver the highest quality
product on-time and for a competitive cost.
