ASME SA240 cold rolled BA finish 304 stainless steel coil roll

Stainless steels are a family of iron based alloys that contain a minimum of 10.5% chromium (CR). The presence of chromium creates an invisible surface film that resists oxidation and makes the material passive or corrosion resistant (stainless). There are multiple families of stainless steel which are designed for various applications and uses. Stainless grades can be further modified to meet various processing, corrosion, temperature and strength conditions.

Stainless steel sheet/Plate can be made by cold rolling and hot rolling, including the thickness of 0.31-6.0 mm sheet and 3.0-60mm plate; common type 201, 202, 304, 304L, 316L, 309S, 310S, 317L, 347, 409L, 410S, 420J1/J2, 430, 446 etc.

Hot-rolled stainless steel, mechanical properties not as good as cold-rolled, but there are good toughness and ductility.
Cold-rolled stainless steel plate due to the good hardening, toughness is low.

In order to ensure all kinds of stainless steel yield strength, tensile strength, elongation and hardness and other mechanical properties to meet the requirements, prior to delivery must be stainless steel annealing, solution treatment, aging heat treatment.

304 stainless steel alleviates this problem by decreasing the carbon content and thereby eliminating the possibility of intergranular corrosion. This low carbon alloy is most often utilized for applications requiring welding. An Extra Low Carbon alloy, Type 304L is also available for especially severe welding applications. Type 304L has the capability to avert any detrimental precipitation in the extreme 800° F. to 1650° F. range.
 
Applications
Both types are extremely popular in the food and dairy industries and for use in pharmaceutical equipment. It is exceedingly useful in applications where good mechanical properties and corrosion resistance are essential. It is highly desirable for products such as instrumentation where non-magnetism is fundamental. These grades are available in a wide range of forms and finishes.
 
Corrosion Resistance
Types 304 and 304L exhibit good corrosion resistant qualities, particularly those corro­sions caused by atmospheric conditions or chemicals. They lose some resistance at temper­atures of about 750° F. to 1500° F. due to carbide precipitation. Type 304L however, has excellent corrosion resistant capabilities within this temperature range because of its low carbon content. Maximum corrosion resistance in all these grades can be achieved by annealing.

FAQ: 

Q: How about the MOQ? If my first order qty is small, will you accept?
A: We would like to do our best to support your trial order qty, so even 1 pc or 1 kg is ok to start cooperation; because we have
confidence to move on second order with your esteemed company.

Q: What is your payment terms ?
A: Commonly two payment term for new customers:
1) 30% T/T as deposit , 70% balance against B/L copy;
2) 100% Irrevocable L/C at sight;
If you need any other terms, pls feel free to contact us too, we will try our best.

Q: How long is your delivery time?
A: Our daily inventory is more than 8000 tons, so for common product size, just need 5 days from stocks; if the special size from
new production, delivery 20-30 days.

Q: How about the samples ? is it free or extra fees?
A: Yes, we would like to supply the samples before order; if the samples from stock, it will be free; if the samples from new
production, we will charge some reasonable cost, but this amount will be deducted from your first order invoice.

Q: How to control and guarantee your shipment quality?
A: 1) All our factories are ISO9001 certified facility; 2) World famous origin mills as TISCO, Baosteel
3) Ex factory inspection by our own laboratory 4) SGS/BV Third party inspection before delivery

Q: Is there any aftersales service? How long guarantee for your product ?
A: Yes, we will provide the after sales service; so if there is any confusion or problem during your usage process, pls feel free
to contact us anytime, we will do our best support.
