What are the Maximum Operating Temperatures of Stainless Steel Grades?

Stainless steels have good strength and good resistance to corrosion and oxidation at elevated temperatures. Stainless steels are used at temperatures up to 1700° F for 304 and 316 and up to 2000 F for the high temperature stainless grade 309(S) and up to 2100° F for 310(S).

What is the Impact of Various Alloying Elements on the Properties of Stainless Steel?

Element Effect on Stainless Steel
Chromium Forms a passive film with oxygen that prevent the further diffusion of oxygen into the surface
Composition needs to contain at least 10.5% to be a stainless steel
Nickel Increases ductility and toughness. Increase corrosion resistance to acids
Additon creates non-magnetic structure
Molybdenum Increases pitting and crevice corrosin resistance. Increase resistance to chlorides
Copper Increase corrosion resistance to sulfuric acid
Manganese Substitute for nickel (200 series)
Titanium/Niobium Ties up carbon and prevents inter-granular corrosion in welded zone of ferritic grades
Nitrogen Increase strength and corrosion resistance in austenitic and duplex grades
Silicon Improves resistance to high temperature scaling
Sulfur Usually kept low excet for “free-machining” grades
Carbon Usually kept low.  Used in martensitic grades to increase strength and hardness

What are the Steel Pipe Sizes?

Steel pipe sizes

Pipe size is quoted as a “Nominal Pipe Size” or NPS. The origin of the NPS numbers for smaller pipes (< NPS 12) is different to the origin for larger diameter pipes. However, all pipes of a specific NPS number have the same external or outer diameter (OD). The internal diameter will vary depending on the wall thickness of the metal. The reason for this is so that the same structural supports can be used for all piping of a specific NPS number regardless of the wall thickness.

Schedules

Steel pipe schedules are a way to describe the wall thickness of the pipe. This is a critical parameter as it is directly related to the strength of the pipe and the suitability for specific applications. A pipe schedule is a dimensionless number and is calculated based on the design formula for wall thickness, given the design pressure and allowable stress.

Examples of schedule numbers are as follows: 5, 5S, 10, 20, 30, 40, 50, 60, 80, 100, 120, 140, 160, STD, XS, and XXS—with the most common being schedules 40 and 80. As the schedule number increases, the wall thickness of the pipe increases. The schedule number of a pipe therefore defines the internal diameter, as the OD is fixed by the NPS number.

How are Steel Pipes Certified?

Certification of Steel Pipes

Manufacturers issue a Material Test Report or Mill Test Report to validate that the product meets the chemical analysis and mechanical properties specification. The MTR will contain all relevant data to the product and will accompany the product through its lifecycle.

The following are typical parameters that may be recorded on an MTR:

  • Chemical composition including carbon content, alloys, and sulfur
  • Material size, weight, identification, and grade
  • Material heat number, which ties back to the processing batch
  • Mechanical properties like tensile strength, yield strength, and elongation

At Metallica, we will Provide you with Original MTR’s for all Stainless Steel Pipe Products! We will Send Our Test Certificates, along with Quotation
