7. SA240 316L Stainless steel plate question:

 

What is dual grade stainless steel?

 

Dual certification refers to two different material or standard certified together to meet both of them, the most common example is 304 and 304L stainless steel grade, that occupy the largest proportion for use in stainless steel, because they have excellent properties to meet the most case

 

What is dual certified 316 316l?

 

316/316L Dual Certified is an extra low carbon version of 316, eliminating harmful carbide precipitation during welding. Also has superior resistance to intergranular corrosion after welding of stress relieving.

 

 

What is the composition of 316 stainless steel?

 

Type 316 steel is an austenitic chromium-nickel stainless steel that contains between two and 3% molybdenum. The molybdenum content increases corrosion resistance, improves resistance to pitting in chloride ion solutions, and increases strength at high temperatures.

 

What is AISI 316 stainless steel?

 

Alloy 316/316L (UNS S31600/ S31603) is a chromium-nickel- molybdenum austenitic stainless steel developed to provide improved corrosion resistance to Alloy 304/304L in moderately corrosive environments. It is often utilized in process streams containing chlorides or halides.

 

What is SA 240 GR 316L?

SA 240 GR 316Lrefers to a grade of austenitic stainless steel plate, certified under the ASME SA-240 standard, with the material grade being 316L.

  • "SA"stands for ASME Section II, Part A, which covers materials used in pressure vessels and boiler applications.
  • 316Lis a low-carbon version of 316 stainless steel, offering excellent corrosion resistance, especially against chlorides and marine environments.
  • Common uses: pressure vessels, heat exchangers, chemical tanks, and marine applications.

What is the difference between ASTM A240 and ASME SA240?

Feature

ASTM A240

ASME SA240

Issuing Body

ASTM International

ASME (American Society of Mechanical Engineers)

Purpose

General specification for stainless steel plate, sheet, and strip

Boiler and pressure vessel quality version of A240

Application

Broad, including general structural use

Specifically for pressure vessels and boilers

Certification

Not necessarily pressure vessel compliant

Mandatory for pressure vessel code compliance (ASME Section VIII)

In essence: The material and chemical composition are the same, but SA240 is used for code-stamped pressure applications, requiring stricter traceability and certification.


What material is ASME SA240?

ASME SA240covers a wide range of austenitic, ferritic, and duplex stainless steel plates, sheets, and strips, used in the fabrication of pressure vessels and boilers.

Example grades under SA240:

  • 304 / 304L
  • 316 / 316L
  • 309S / 310S
  • 321 / 347
  • 2205 (duplex)
  • 904L (super austenitic)

So, ASME SA240 is a specification, and the material is defined by the grade — for example, SA240 316L means stainless steel 316L plate for pressure vessels.


 What is the ASTM grade for 316L?

The ASTM grade for 316L stainless steel plate is:

ASTM A240 Grade 316L

It refers to low-carbon austenitic stainless steel with:

  • Carbon content ≤ 0.03%
  • Better weldability
  • Excellent corrosion resistance, especially against pitting in chloride environments

What is SA 240 GR 316L equivalent?

SA 240 GR 316L is equivalent to the following international standards:
