Nitronic 50 Round Bars, Sheets and Plates: Sizes, Standards and Procurement Guide

Nitronic 50 Round Bars Nitronic 50, also known as UNS S20910 and XM-19, is a nitrogen-strengthened austenitic stainless steel used in demanding industrial and engineering applications. Its combination of strength and corrosion resistance makes it a material worth considering for selected marine equipment, chemical processing components, pump assemblies, shafts and specialised machinery.

For procurement teams, selecting the correct Nitronic 50 round bar, sheet or plate involves more than identifying the alloy grade. Buyers must also confirm product dimensions, material condition, applicable standards, testing requirements and documentation.

This guide explains the important considerations when sourcing Nitronic 50 in different product forms.

Understanding Nitronic 50 Material

Nitronic 50 is an austenitic stainless steel alloy containing chromium, nickel, molybdenum, manganese and nitrogen.

It is commonly identified by:

  • Material name: Nitronic 50
  • UNS designation: S20910
  • Common designation: XM-19
  • Material family: Nitrogen-strengthened austenitic stainless steel

The material is considered for applications requiring a combination of mechanical strength and corrosion resistance. Actual performance depends on the supplied condition, manufacturing process and service environment.

Nitronic 50 Product Forms

Nitronic 50 may be specified in different product forms according to the component design and manufacturing requirements.

1. Nitronic 50 Round Bar

<PRIVATE_PERSON>itronic 50 round bars are considered for machined and engineered components where strength and corrosion resistance are important.

Potential applications include:

  • Industrial shafts
  • Pump components
  • Valve components
  • Mechanical fasteners
  • Machined engineering parts
  • Specialised equipment components

When ordering round bars, specify the diameter, length, quantity, material condition and applicable specification.

2. Nitronic 50 Sheet

Nitronic 50 sheet may be considered for selected fabricated components and equipment parts.

Buyers should specify:

  • Required thickness
  • Width and length
  • Material condition
  • Surface finish, if specified
  • Applicable product standard
  • Inspection and documentation requirements

The suitability of the sheet for forming, welding or other fabrication operations should be assessed before production.

3. Nitronic 50 Plate

Nitronic 50 plate may be specified for engineered components and fabrication requirements where the required thickness and product form are covered by the relevant material specification.

Before placing an order, confirm the required plate dimensions, thickness tolerance, material condition and testing requirements.

Important: Product forms and their standard coverage should be verified against the exact grade and applicable specification. Do not assume that every Nitronic 50 product form is covered by the same ASTM standard.

Nitronic 50 Sizes: What Should Buyers Specify?

There is no single universal size range that applies to every Nitronic 50 supplier or product specification.

The required dimensions should be communicated clearly so that the supplier can check availability and confirm whether the requirement can be met.

Product formImportant size details
Round BarDiameter and length
SheetThickness, width and length
PlateThickness, width and length

For special requirements, buyers should also mention:

  • Required dimensional tolerances
  • Cut-to-length requirements
  • Surface finish
  • Straightness requirements for bars
  • Machining allowance, if needed
  • Quantity and delivery expectations

Actual availability and achievable tolerances must be confirmed before order placement.

Nitronic 50 Round Bar Weight Calculation

For preliminary estimation, the weight of a cylindrical round bar can be calculated using its diameter, length and material density.

Formula:

Weight (kg) = 0.0007854 × D² × L × Density

Where:

  • D = Diameter in mm
  • L = Length in metres
  • Density = Material density in g/cm³

Use the density value stated in the applicable material technical data or supplier documentation. The result is an estimate; actual weight may vary with dimensions and manufacturing tolerances.

For other steel and stainless steel round bar calculations, refer to the Round Bar Weight Chart.

Nitronic 50 Standards and Specifications

Material standards are important because they define requirements relating to chemical composition, mechanical properties, dimensions, testing and product condition.

The following standards may be relevant to certain stainless steel product forms:

StandardGeneral product scope
ASTM A276/A276MStainless steel bars and shapes
ASTM A479/A479MStainless steel bars and shapes for pressure vessels and related applications
ASTM A240/A240MChromium and chromium-nickel stainless steel plate, sheet and strip

Important: The applicability of a particular standard to Nitronic 50 must be confirmed for the exact product form, grade designation, condition and current specification revision. Do not assume that a standard automatically covers every product form or supply condition.

For technical verification, consult:

Nitronic 50 Material Certificates and Inspection

For industrial procurement, material documentation helps buyers verify that the supplied material meets the agreed purchase requirements.

Depending on the order and application, buyers may request:

  • Material Test Certificate (MTC)
  • Chemical composition report
  • Mechanical test results
  • Heat number and material traceability
  • Dimensional inspection report
  • Hardness test results, where specified
  • Additional inspection or testing required by the purchase order

Always check that the certificate identifies the correct grade, product form, specification, condition and heat number.

For critical applications, agree on inspection and testing requirements before confirming the purchase.

How to Select the Correct Nitronic 50 Product

Choosing between a round bar, sheet and plate depends on the component design and manufacturing process.

Choose round bars when:

  • The component requires turning, drilling or machining.
  • The design involves shafts, pins or cylindrical parts.
  • A specific bar diameter and length are required.

Consider sheets when:

  • The component is designed around thinner flat material.
  • Cutting or forming operations are required.
  • The required thickness and finish are available in the specified product form.

Consider plates when:

  • The component requires a thicker flat product.
  • Fabrication or machining requires a plate form.
  • The design specifies particular thickness and dimensional tolerances.

The final selection should be based on engineering calculations, the applicable material specification and the actual operating environment.
