View Astm A240 Plate Thickness Chart In Mm and SS 304 Sheet Flatness Tolerance Chart/ Gauge in Mm

 

Many Steel stockholders generally stock a range of Stainless Steel standard size plate as this increases the availability and likelihood that you will able to find the Stainless Steel Plate that you need. To maximise the benefit of purchasing Stainless Steel Plate from a stockholder it is best to design to use stock plates. That is if you know what dimensions are available you can minimise wastage and cutting in your design.

It is also beneficial to consider the dimensions that a stockholder works in. This is because there is not an exact correlation between metric and imperial units and there can easily be a 10% difference in the closest Stainless Steel Plate sizes to your dimensions leading to increased wastage.

 

What does tolerance mean in Stainless Steel Plate?

The tolerance basically indicates the range wherein dimension is acceptable for a specified design. For example, if a product which has 2 inch dimension and tolerance of ± .05 inches, then the acceptable range will be 1.95 to 2.05 inches. Clients can take a look at the Stainless Steel Plate Thickness Tolerance Chart to understand the range of allowable thickness for the plate and customize their products accordingly. The SS Plate Standard Size Chart would help to understand the allowable range or tolerance of the plate, at a glance.

 

Is tolerance for SS Plate thickness?

Yes, clients can find Stainless Steel Plate Thickness Chart In Mm, and thus, the tolerance for SS Plate thickness. The thickness is measured along the longitudinal edges for the plate which is at least 9.5mm or 3/8inches. But the Astm A480 Thickness Tolerance should not exceed 76.20mm or 3 inches from the edge. Also, the plates which are 10 254mm or 10 inches in thickness, the tolerance under specified thickness is around 0.25mm or 0.010 inches.

 

How is SS 304 Plate Flatness tolerance calculated?

Just like there is a 304 Stainless Steel Plate Thickness Chart, clients can also take a look at the Astm A240 Plate Flatness Tolerance Chart for their convenience. Considering a specific thickness, there is a flatness tolerance for thickness for each of the dimensions.

 

What are SS Plate gauges?

The SS plate gauge is basically the thickness of the metal. For stainless steel products, it is measured in gauge. Clients can take a look at the Stainless Steel Plate Gauge Chart to get a clear understanding of the dimensions, and buy products that would suit their needs. However, when considering the SS 304 Sheet Flatness Tolerance Chart, it is essential to remember that higher the number, the thinner is the stainless steel. It means that the 12 gauge is much thicker than the 18 gauge plate.

304l Stainless Steel Plate Value Added Service

The following value added services can be provided by Sanghvi Enterprise Products in order to meet the exact specifications of your stainless steel plate requirements.

Stainless Steel Plate Polishing Almost every stainless steel plate item can be polished to a #4 polish, #6 polish, #7 polish, or #8 mirror shine. One or both sides of stainless plates can be polished. Polished stainless steel plates can also be trimmed to size. Surfaces that are free of pits can also be given.
Stainless Steel Plate Beveling To prepare stainless steel plate for welding or other procedures, we can bevel the edges.
Blanchard grinding In some applications, the flatness of stainless steel plates is crucial. Sanghvi Enterprise may blanchard grind stainless steel plates at the request of the customer.
Heatreating & Annealing The mechanical characteristics of some stainless steel plates can be altered by heat treatment. Stainless steels that have been precipitation hardened, such as 17-4PH, can be heat treated. Heatreated 410 stainless steel plate is also available. Depending on the application, secondary annealing of 300 series stainless steel may be required.
Positive Material Identification (PMI) For most stainless steel grades, Sanghvi Enterprise can undertake PMI testing in-house, or we can partner with outside labs to complete PMI to match customer specifications.
UT Testing UT testing of stainless steel plates may be required in specific instances. This is something we can help you with.

  •  Tolerance in this table apply to any length, not necessarily the rolling direction, up to 36 in. (914 mm) of the longer lengths in the plane of the plate measured while the plate rests on a flat surface with the concavity of the curvature upward.
  •  If the longer dimensions are under 36 in. (914 mm), the tolerance is not greater then 1/4 in. (6.4mm).
  •  For plates with specified minimum yield strengths of 35 ski (240 MPa) or more, the permitted variations are increased to 1 1/2 times the amounts shown.

Steel Plate ASTM Specification

ASTM Plate Specifications

ASTM A167 Stainless and heat-resistant chromium-nickel steel plate, sheet, and strip, as well as numerous stainless steel grades, are covered by this specification. Because ASTM A 240 encompasses much of the same information and criteria as ASTM A167, this specification is rarely used for stainless steel plate goods. This specification is now compliant with the A480/A480M criteria.
ASTM A176 Stainless steel and heat-resistant chromium-nickel steel plate, sheet, and strip are covered under this ASTM Specification. Many grade-specific criteria were superseded or merged into ASTM A 240, similar to ASTM A167. This specification is now compliant with the A480/A480M criteria.
ASTM A240 This specification governs a set of general requirements for stainless steel plate, sheet, and strip, comprising ASTM specifications A167, A240/A240M, A176, A264, A263, A265, A693, A793, A666, A693, and A895. The thickness tolerances and manufacturing standards for stainless steel plate are covered by ASTM A480.
ASTM A693 Precipitation-hardening stainless steel plate, sheet, and strip are covered by this ASTM specification. ASTM A693 covers 17-4Ph stainless steel, for example.
ASTM A480 For 300 series stainless steels, this is the most commonly mentioned stainless steel plate specification. For common applications, this specification includes chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip.
