Better Touch Better Business
We are capable of providing stainless steel spheres/balls almost as per your specific requirements. Products include hollow stainless steel spheres (ranging from 6mm to 2500mm in diameter), available for delivery if we have it in stock or delivered within 15 days. Wall thickness of spheres varies from 0.4mm to 3mm. Shaped by water pressure, our products could be mirror polished without any seams noticeable on the surface; meanwhile, welding and then sandblasting spheres is a another way to produce mirror polished spheres also without detectable traces on the spheres. Having been offering services for our customers worldwide, a variety of products also fall under many categories of our products. Staidness steel spheres, hollow or solid, of all sizes are our major products, and brass and bronze balls come along. Hollow reflective stainless steel spheres of enormous sizes are amongst the top sales in our products. Perforated stainless steel spheres or sculptures of 304 or 316 are also our hot products. Not to mention we have done considerable amount of drilled stainless steel balls or spheres with holes of many sizes. Our products are of professional and advanced technology with cost-effective craftmanship and favorable delivery time.
Stainless steel sculpture packing:
2CM standard wooden crate with metal junction and nails;
Enough wood chunks as support for the inner products;
Three strong strapping packing belts around the wooden crate ;
Thick plastic or soft foam to avoid scratches on the surface of the ball;
Shockproof foam to protect each carved garden ball for decoration.
Types 304 and 304L exhibit excellent resistance to corrosive
environments such as the chemical, textile and petroleum industries.
Type 304 and 304L are found suitable in the food and dairy industries
as well as excelling in rural and industrial atmospheric exposure.
By reducing the carbon content in Type 304L, welding operations will
not cause carbide precipitation that can lead to intergranular corrosion.
The maximum temperature to which Type 304 can be exposed
continuously without appreciable scaling is about 1650 °F (899 °C).
For intermittent cyclic exposure, the maximum exposure temperature
is about 1500 °F (816 °C).
Type 304 is non-hardenable by heat treatment.
Annealing: Heat to 1900 – 2050 °F (1038 – 1121 °C), then cool rapidly.
Thin strip sections may be air cooled, but heavy sections should be water
quenched to minimize exposure in the carbide precipitation region.
Stress Relief Annealing: Cold worked parts should be stress relieved at
750 °F (399 °C) for 1/2 to 2 hours.
High hardness and strength are achieved through cold working. In
the annealed condition, Types 304 and 304L are very ductile and can
be cold worked easily by roll forming, deep drawing, bending, and
other common fabricating methods. Since the material work hardens
rapidly, in-process annealing may be necessary to restore ductility
and to lower hardness.
Types 304 and 304L can be readily formed and drawn. The higher
nickel versions of Type 304 are well suited to severe forming
applications involving multi-draw operations and forming of complex
shapes. This is largely due to its combination of lower strength and
lower work hardening rate. As with all austenitic stainless steels,
annealing or stress-relieving can be performed following fabrication.
The austenitic class of stainless steels is generally considered to be
weldable by the common fusion and resistance techniques. Special
consideration is required to avoid weld “hot cracking” by assuring
formation of ferrite in the weld deposit. Type 304 and 304L are
generally considered to be the most common alloys of this stainless
class. When a weld filler is needed, AWS E/ER 308, 308L or 347 are
most often specified.
