What are 253MA Plates & Sheets?

So, what exactly is 253MA? Think of it as a clever evolution in heat-resistant stainless steel. Carrying the designations UNS S30815 and EN 1.4835, it's an austenitic alloy, but its real strength lies in a carefully optimized chemical recipe. Beyond the typical chromium and nickel, 253MA includes strategic amounts of nitrogen, silicon, and rare earth elements like cerium.

Why does this specific blend matter so much? It delivers some very practical advantages in tough conditions:

1. Stands Up Strong Against Oxidation: The teamwork between silicon and cerium is remarkable. Together, they help form a highly stable and adherent protective oxide layer on the steel's surface. This shield performs admirably, especially under the stress of heating and cooling cycles, offering solid protection against oxidation in air at temperatures reaching up to about 1150°C (2100°F).
2. Maintains Strength When Hot: Adding nitrogen, alongside carbon, significantly bolsters the alloy's ability to resist creep – that slow stretching that can occur under load at high temperatures. In practice, this means components made from 253MA hold their shape and integrity longer, extending service life considerably.
3. Handles Certain Tough Atmospheres: Compared to grades with much higher nickel content (like 310), 253MA often fares better in reducing environments where sulfur is present. It also holds its own in atmospheres containing carbon and nitrogen, conditions that can challenge some other alloys.
4. Resists Embrittlement: The carefully balanced composition helps prevent the formation of sigma phase, a brittle structure that can sometimes form in stainless steels after prolonged exposure to intermediate temperatures. This enhanced stability means less worry about the material losing toughness over time.
5. Offers Economic Advantages: Because nickel is a significant cost driver in alloys, 253MA's leaner nickel content often makes Alloy 253MA Sheet and plate a more budget-friendly choice than higher-nickel alternatives, without making major sacrifices in essential high-temperature performance.
6. Fabricator-Friendly: Good news for welders: 253MA generally behaves like familiar austenitic stainless steels during fabrication. Standard welding techniques work well, though for the best results, especially concerning high-temperature strength in the weld, using recommended filler metals (such as 22.12.HT) is advisable.

Essentially, 253MA Plates & Sheets occupy a crucial space, offering a step up from standard stainless grades and providing a potent, often more economical, alternative to high-nickel alloys for challenging thermal processing needs.

Chemical Composition and Mechanical Properties

The performance profile of UNS S30815 Plates is a direct result of its specific chemical ingredients and the mechanical strength derived from them, particularly under heat.

Chemical Composition (Typical)

Getting the elemental balance right is what gives 253MA its high-temperature prowess. A typical composition looks like this:

Element	Symbol	Typical % Range	Contribution to Performance
Chromium	Cr	20.0 - 22.0	The cornerstone for fighting oxidation and general corrosion.
Nickel	Ni	10.0 - 12.0	Key for the stable austenitic structure, adds toughness, aids hot strength.
Silicon	Si	1.40 - 2.00	Dramatically improves oxidation resistance, especially working with Ce.
Nitrogen	N	0.14 - 0.20	A powerful strengthener at high temps, significantly boosting creep resistance.
Cerium	Ce	0.03 - 0.08	Enhances the protective oxide scale's adherence, vital under thermal cycling.
Carbon	C	0.05 - 0.10	Adds to high-temperature strength, balanced with Nitrogen's effect.
Manganese	Mn	≤ 0.80	Helps during the steel production process.
Phosphorus	P	≤ 0.040	An impurity element, kept to a minimum.
Sulfur	S	≤ 0.030	Another impurity, levels are restricted for optimal properties.
Iron	Fe	Balance	The fundamental base metal providing the alloy's structure.

Note: These percentages represent typical ranges per ASTM A240. While slight variations exist between different production batches (heats), all material will conform to the certified standard.

Mechanical Properties

While room temperature data provides a starting point, the true measure of ASTM A240 253MA Plate is its behavior when things get hot.

Typical Room Temperature Mechanical Properties:

Property	Typical Value	Units	Reference Standard
Ultimate Tensile Strength	650 (95)	MPa (ksi)	ASTM A240
0.2% Offset Yield Strength	310 (45)	MPa (ksi)	ASTM A240
Elongation (in 2" or 50mm)	40	%	ASTM A240
Hardness (Approximate)	95	Rockwell B
217	Brinell (HB)
Density	7.8	g/cm³
Melting Range	1371 - 1432 (2500-2610)	°C (°F)

The High-Temperature Advantage:

Let's be clear: 253MA earns its keep in heated environments. Its most compelling mechanical characteristic is its excellent creep rupture strength. This resistance to slow deformation under sustained stress at high temperatures significantly outperforms common grades like 304 or 316, and frequently surpasses even 310 stainless steel, especially within the 850°C to 1100°C (1560°F - 2010°F) range. What does this mean for you? Longer lasting components in your high-temperature equipment. Additionally, its austenitic nature ensures it remains tough and resists becoming brittle, even at cryogenic temperatures.

For detailed engineering calculations involving performance under heat, consulting specific creep and stress rupture data charts is crucial. The technical team at USA Piping Solution is ready to assist in providing this necessary data for your specific operating conditions.

Types and Variations of 253MA Plates & Sheets

USA Piping Solution supplies 253MA / UNS S30815 in the formats manufacturers need most:

• 253MA Plates: Generally refers to the thicker material (starting around 3/16" or 4.8mm), typically hot-rolled, annealed, and pickled (HRAP or No. 1 finish). This is the workhorse for structural elements, heavy furnace parts, and applications demanding substantial material thickness. Standard and custom-cut sizes are available.
• 253MA Sheets: Thinner gauge material, often produced via cold rolling. This process allows for smoother surface finishes (like the common 2B matte or brighter BA finishes) and tighter control over thickness. Sheets find use in liners, heat shields, expansion joints, and lighter fabricated items.
• 253MA Coils: For high-volume production or continuous processes, 253MA sheet or strip can be supplied in large coils. This format is efficient for automated lines producing things like tubing or long components, and can be slit down to specific widths.
• 253MA Strip: Narrower sections precisely slit from coil. Strip is often destined for specific parts like high-temperature seals, gaskets, clamps, or smaller formed components.
• Specialty Forms (Upon Request):
• Perforated 253MA Sheet: We can facilitate the supply of sheets with punched hole patterns for applications needing airflow or drainage at high temperatures, such as industrial baskets, trays, or screens.
• 253MA Chequered Plate: Plate featuring a raised pattern for grip can also be sourced, although less common for primary high-temp structural roles compared to flat plate.

We focus on providing the material in the most efficient form for your fabrication process. Discuss your specific needs with us.
