Please comment if the below indicated +10% and +13% are correct, respectively + how many % would that be, roughly?
50 - 199 mm
200 - 599 mm
+13%
+10%
*Additional cost for Non-standard sizes
About unregular sizes, it depends on the actual width . How much the wastage there would be appear.
The regular width are 485mm, 510mm, 550mm, 620mm, 650mm, 690mm, 730mm.
For example, if need 220mm, then we'll use 485mm master coil, then we have to slit 10mm away, the extra cost is around USD50/TON including slit charge.
It can not be indicated by %. You can proposal that if 10mm wastage, then add USD50, for example.
The same formula applies to both aisi 201 and 304?
For 304 only.
For 201, it is around USD35.
2BB production:
aisi 430 = 80% brightness of BA ( BA min gloss 530)
aisi 304 = 60% brightness of BA ( BA min gloss 570)
Please note that our 2BB is particularly good in scotch bright, ddq, tube applications etc and we have been shipping substantial quantise of aisi 304 2BB 0.9-1.9 * 1219 to italy for over a year now.
For 2BB, it is usd 50 pmt less.
OD means the outside diameter of the core of the coil. It is normally 508 or 610 mm. He says larger OD means 610 mm.

In Wuxi, we purchase :
no.1 coil in aisi 304 and convert it to 2BB / BA.
Black coil in aisi 410 / 430 and convert to no.1, then to 2BB / BA.
Therefore, our aisi 400 series is more competitive eg Korea Posco is famous for BA but we have been exporting to the Koean customers continuously.

Any standard coil weight for Wuxi? What's the minimum and maximum? ANY CWT. BUT IF 2.8 MT +LIGHTER NEEDS USD $) PMT EXTRA
2BB is 80% brightness of BA but we are selling at the cost of 2B right? YES. 304is 60% brightness and 430 is 80%.
Wuxi purchases hot rolled coil from e.g. Baosteel, POSCO, LISCO, TSINGSHAN, SOUTH WEST etc? YES, all reputable ss plants
No. 1 coil and no. 4 finish, PVC, hairline, all available from Wuxi? YES. no.1 = trading as we buy it regularly for ourselves and we have excess for export. We can also order special specifications/dimensionsfrom the mills. All others are available.
What is "film"? PVC ( plastic vinyl coating )
What is 8K / 8K fine grinding? Our BA is 6K, BAA is 8K ( mirror brighter with usd 80 pmt on top of BA ). Usually just BA is good enough.
Can Wuxi produce any thickness less than 0.25mm or above 2mm? 0.25 - 2.2 mm
Can Wuxi produce any width less than 50mm? 25 mm+up
These are the ONLY grades available from Wuxi right : 201, 304(L), 316(L), 410, 430? YES, more than enough.
What is 410S? SAME?SIMILAR AS 410. I DO NOT KNOW EITHER BUT I HAVE ORDERS REGULARLY.
aisi 304 2BB, brightness 60% of BA ( Italy has received several thousand tons for applications like ddq, scotch brite, tube etc )
aisi 430 2BB,brightness 80% of BA ( Also Italy took it as BA )
F1 / aisi 201 ( 1% ni)
F4 ( aisi 202) ( 4% ni )
aisi 301J ( 6% ni )
aisi 304 ( 8% ni )
aisi 316L ( 10-10.5% ni.)
