Some are offer improved corrosion resistance. Good weldability. But stainless steel isn’t a single alloy. Older grades often feature a three-digit identifier established by the Society of Automotive Engineers (SAE). Heat-based hardening will not work with these types of steel. To truly understand what separates one type of stainless steel from another, you’ll need to look at its grade. Its uses in the transportation industry are typically reserved for heavy-duty equipment, such as tanker trucks, ship containers, chemical tankers, and garbage trucks, used for the transport of bulky or corrosive materials. To make an informed decision when purchasing food grade stainless steel equipment, you should understand the major elements in the alloy, the different grading systems, and the main types of stainless steel. Compared to 304, 316 is less commonly used. 304 is the most commonly used austenitic stainless steel. Stainless steel finds application in a wide range of industries, including: As stainless steel is highly durable and impervious to rust, it is frequently used for a variety of architectural components, including cladding, handrails, fittings for doors and windows, street furniture, rebar, lighting fixtures, and masonry supports. 15-5 has exceptional corrosion resistance and durability. There’s two main labels you’ll find on most stainless steel alloys: But what can you learn about these alloys from their labels? Stainless steel is prized in the chemical industry for its tensile strength and chemical resistance. The most common type of steel, austenitic stainless steels contain nickel, manganese, nitrogen, and sometimes molybdenum in addition to iron and chromium. Stainless steel is found in a number of construction parts and products due to its high durability and corrosion resistance. Tempering and hardening is possible due to added carbon, making this family a leading choice for knives, scissors, razors and medical tools. These stainless steel alloys offer moderate to good corrosion resistance and remain magnetic after hardening. We offer the following grades of duplex steel: 2205 and 2207 are widely used grades of duplex stainless steel. The abrasion resistance and fatigue strength are superior to 304 stainless steel.302 stainless steelTh… While all stainless steels have at least 10.5% chromium content, alloys with higher percentages demonstrate greater corrosion resistance. These are known as Unified Number System (UNS) identifiers. It is also valued in architectural design for its aesthetic appearance. While low on nickel, these alloys often chromium, molybdenum, niobium and/or titanium to improve toughness and improve creep resistance. Hence, the knowledge of its grades/types, application, advantages and disadvantages of this important material is required for its safe and hygiene use … Stainless steel is an iron alloy composed primarily of iron and chromium. Common grades of martensitic and precipitation hardening steels include 410 and 420 grades. The alloy contains more molybdenum and nickel and is available in a low carbon variation—316L. 304 finds use in a variety of industries, including automotive, food and beverage, nuclear, and shipping, while 304L is generally used in welding applications. This family is the most popular and widely used around the world. Required fields are marked *. Its uses include offshore oil and gas and nuclear waste processing applications. These alloys cannot be hardened through heat treatments but can be work hardened. We distribute the following grades: 410 is durable and highly resistant to wear but is more susceptible to chemical corrosion and oxidation. While stainless steel gets a large part of its corrosion resistance from chromium, there are near-endless combinations of various metals marketed as stainless steel today. Learn more. Ferritic steels feature high chromium contents and low carbon contents (usually less than 0.10%). 304L is a variation that has a lower carbon content. Many different types of stainless steel grades are used in foodservice establishments, and each type has its own pros and cons. 304L is a variation that has a lower carbon content. Your email address will not be published. For example, 304 stainless steel by the SAE standard might also be graded as: However, to receive a given grade designation, the alloy must adhere to a strict set of requirements set forth by the organization maintaining the standard. At Bergsen, we are committed to producing the best quality stainless steel for all industries. We offer the following grades: Due to its sulfur and phosphorus content, 303 stainless steel is highly machinable. Characteristics depend on the alloy as many are created to address specific industrial concerns, such as weight, toughness and higher tensile strength.
