Yes pool steps are fiberglass, with a top coating to water proof them. I would get a 2 part resin compound or go to a marina if you are near any and they have fiberglass repair kits. A 2 part resin should seal the cracks as well. You obviously will need to lower the water level below cracks allow steps to dry then follow directions for the resin application let that set up 24 hrs then re-fill pool.
Well I have had some great success with a product called schmere it is a PVC pellet product when mixed with primer will turn into a paste substance, then you trowel it on any plastic surface and smooth out then when dries it turns to plastic again. I have used it on pool skimmers for many years and works great, so if your steps are plastic then it will work.
