You can use steel shot with a choke anywhere from cylinder to modified, i wouldn't recommend using steel with a improved modified or a full choke.
One not designed for use with steel shot.
use lead only steel chokes are specified on the choke as steel of lead shot
full choke
full choke
The use of steel shot doesn't directly have anything to do with a "Belgium" made shotgun barrel. The only significance is that the gun/barrel was manufactured in in Belgium. The problem with steel shot can be a problem with any shotgun made before the steel shot came into use. The problem has to do with the choke. The use of lead shot shells didn't pose a problem because lead is soft compared to steel. The choke is a constriction at the end of the barrel that can change the shot pattern of the shot shell pellets. The inside diameter of a typical 12 gauge shotgun is about .726 +or- a few thousandths. The constriction of a full choke is about .030 thousandths tighter with a diameter of about .696 Steel shot doesn't compress the same a lead and as a result can damage an older gun not designed for steel shot. Most older guns can handle steel shot if they have a more open choke for example an Improved Cylinder choke. Another alternative is to use another non-lead alternative ie. bismuth. Even with new guns you shouldn't use Full Choke with steel. Modified Choke will generally produce relatively tight patterns with steel. If the gun has some collector value, don't take a chance. If you are determined to hunt with it and want to shoot steel shot, see a gun barrel specialist like Ballistic Specialties in Batesville Arkansas. They can do anything just about with a shotgun barrel.
A full or extra full choke will hold shot in a tighter pattern

C-lect choke is an adjustable choke system that Mossberg implemented on their shotguns pre-1977. After 1977 they went to the accu-choke system. The choke is adjustable between Full, Modified, and Improved Cylinder. It is, however, not recommended for use with steel shot.
You must call Browning in order to make sure you don't void your warranty.
Yes certainly it can with barrels intended for steel. It is generally not reccomended to shoot steel through Belgian FN guns no matter the choke. If you have a Japanese made gun with the invector choke system it is likely ok, but not certain. Check the year and be certain that the (invector) choke is rated for steel. The best reccomendation is to consult Browning with the year your gun was made (by serial number) and the barrel markings to identify the time period the barrel was made. They are best suited to recommend a safe answer to this question. Auto5man
I bought a 1400 mk 2 non ribbed 12 ga. yesterday for $165.00 US
For the BEST answer, contact Browning Customer Service through their website. SOME older shotguns should not use steel shot, due to wear at the choke. Some will handle it fine. Browning should be able to give you the definitive answer. FWIW, there ARE alternatives to steel shot in a lead-free zone- bismuth for one.
