Bespoke 1000mm large stainless steel hollow spheres sculpture
1000mm large stainless steel hollow spheres sculpture
Q: Do you have a stainless steel ball of 500mm?
A: As for those standard sizes, we always have stock.
Q: Do you have a 1000mm ball ? How long can I get it?
A: This ball falls into a category of big size sphere, so it takes some time in manufacturing and delivery.But rest assured you could get it as soon as possible.
Q: Can I have a stainless sphere not of regular sizes?
A: Sizes not of standard are available bur it costs a fortune. Hence, it is not recommended by us. With modest money, we could always provide you with sizes sim lar without too many differences and the quality remains unchanged.
Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
