Yes, you can trade lots of stuff with other players. But some items are "bound", meaning that they are attached to you and cannot be traded to other players.
When you mouse over a weapon or armor piece, it will usually say something like "This item is bound to you" or "This item will bind to you when equipped". As soon as you equip a weapon or armor piece, it is bound to you. Some items are bound to you even before you equip/use them: tokens, weapons and armor earned though boss tokens, recipes purchased in the Hall of Heroes, mist tanks, etc.
Weapons and armor can be unbound at Punch/Vise in the Bazaar. The unbinding fee for high-star items is truly enormous. In order to craft a 4-star item, its 3-star precursor must be heated to heat level 5, and hence must be equipped, and hence must be bound. These two aspects of the game design make it somewhat impractical to buy high-star items.
