ASME SA516 Gr. 70 SA-516-70N Dished Elliptical Head End Caps,DIN 28013 Ellipsoidal heads
We are the professional manufacturer of ASME SA516 Gr. 70 ,SA-516-70N Dished Elliptical Head End Caps,DIN 28013 Ellipsoidal heads in China.
2:1 elliptical heads
A516 Gr70 not only has very high strength but also has very good toughness, wear resistance, fatigue resistance, impact resistance, welding ease of processing and cold forming properties.
Elliptical heads (also known as ellipsoidal heads or elliptical dish ends) are typically made of carbon steel, stainless steel, austenitic and cold workable metals. This elliptical head shape is more economical because the height of the head is only a fraction of the diameter.

We supply elliptical heads made of carbon steel and roll-bonded clad plates. They are available as single-piece, single-piece with a weld seam
and multi-piece heads. Single-piece elliptical heads are produced by hot pressing and can be dished and flanged. Multi-piece elliptical heads
(crowns and segments) are pressed .
We are able to provide our customers with a wide range of high-quality products.

ASME SA516 grade introduction:
SA516 grade 55, SA516 grade 60, SA516 grade 65, SA516 grade 70. These 4 grades are mainly defined by their different tensile and yield strength range, which is influenced by content of Carbon. For example sa 516 grade 70 has the highest tensile and yield strength range due to the highest Carbon content(up to0.28%). For higher grade like sa516 gr-70 steel plate, preheating might be needed for metal arc welding process, especialy with thick steel plate.
