Hopefully a simple change that could be implemented, but currently greensteel items have material type of steel with a hardness of 15 - with the way randomly generated items are scaled now, it this means that comparatively they're about as solid as cheese - and not a fine Parmigiano but more like a delicious, crumbly Wensleydale which might be fine as a treat for Gromit the rust monster but for practical purposes it's somewhat lacking - maybe it could be achieved by adding greensteel as a specific independent material type, or the greensteel property on items could add extra hardness & durability but through whatever method increase the hardness to about 30 so they can actually last through more than one quest? The adamantine ritual is nice enough, but it's only +5 hardness which doesn't help all that much & subsequent ones only add durability not more hardness too.
