ASTM A240 316L,Stainless Steel Plate,ASTM A240 316L Plate,SA240 316L Strip,ASTM A240 316L Sheet,SA240 316L Plate
ASTM A240 TP316L Plate for pressure vessel/ASTM A240 316L Plate is mainly used for the field which has a high request for corrosion resistance,Like pressure vessel.
ASTM A240 316L is part of the austenitic family of stainless steel and is the most widely used varieties of stainless plate. 316 grades contain a higher level of Nickel than 304 giving it an improved corrosion resistance over 304 grades. 316/316L plate is a good option for marine applications due to a good atmospheric corrosion resistance. 316L is a low carbon modification to 316 grade.
A240 316L stainless steel plate is the standard molybdenum-bearing grade of stainless steel plate. The molybdenum gives 316 stainless steel plate better overall corrosion resistant properties than grade 304 stainless steel plate. It has particularly higher resistance to pitting and crevice corrosion in chloride environments. 316 stainless steel plate has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 stainless steel plate also has outstanding welding characteristics. Grade 316L stainless steel plate is the low carbon version of 316 stainless steel plate and is extensively used in heavy gauge welded components.
A240 316L plate has many applications,can be used to make the welded pipe,fittings,and heat exchanger shells,tanks etc.

* Thickness is measured along the longitudinal edges of the plate at least 3/8 in. [9.52mm], but not more than 3 in. [76.20 mm], from the edge.
** For plates up to 10 in. [254.0mm], excl, in thickness, the tolerance under the specified thickness is 0.010 in. [0.25 mm].
*** For circles, the over thickness tolerances in this table apply to the diameter of the circle corresponding to the width ranges shown. For plates of irregular shape, the over thickness tolerances apply to the greatest width corresponding to the width ranges shown.
Below is the Tolerance for Flatness taken from ASTM A480
(Understand that this covers Mill Plates and not cut pieces)
Table A2.20 Permitted Variations in Flatness of Plate Mill Plate (Quarto Plate)
Note 1 — Tolerances in this table apply to any length, not necessarily the rolling direction, up to 36 in. [914mm] and to any 36 in. [914mm] of longer lengths in the plane of the plate measured while the plate rests on a flat surface with the concavity of the curvature upward.
Note 2 — If the longer dimension is under 36 in. [914mm], the tolerance is not greater than 1/4 in. [6.4mm].
Note 3 — for plates with specified minimum yield strengths of 35 ksi [240MPa] or more, the permitted variations are increased to 1 1/2 times the amounts shown.
