"Around the middle of the eleventh century the Greeks themselves may have begun making iron swords, knives, daggers and pins, from local ores (Snodgrass 197I: 221 sqq.). For the time being iron did not yet surpass bronze in all respects. The hardness of the entire objects was often less than that of bronze objects, and the toughness of later steel objects was unknown as yet. For about one or two centuries no great technological progress seems to have been made. It is with new techniques – quenching, and piling together thin laminations of carburized iron – that the quality of iron (steel) objects increases in such a way as to make a lasting impact on technology (it is not known how early the technique of tempering became known; Wootz steel and pattern-welded true damascene steel [Coghlan 1956: I55–65] were not yet fabricated by the Greeks)."
it progresses very slowly and not everyone has the same speed.
Besides, even nowadays we have problems with the quality of the metal produced (when we buy it cheap in a country that does not bother to sell their shit)
I know someone who works for Alstom, on a Chinese dam and he was later called on other hydroelectric dams (copies of the one he had made) which was not supervised by them and the problem he had was the lack of quality of the metal and the precision of the finish.

It is important to know that knowledge is lost regularly throughout history and that techniques are well-kept secrets
moreover in the middle ages many weapons and armor had no heat treatment, or control of carbon concentration, there was no standard, yet some knew how to do it, but others did not know or have forgotten for one reason or another
Maybe his master only made weapons and armor for people who did not have the financial means (and yes it is more expensive, because there is more work, more resources and the technique is harder to master, especially without a thermometer and above all the technique is different for each type of weapon, or piece of armor, because you are not looking for the same hardness, nor the same depth of hardness, carbon concentration and depth of the concentration)
and he therefore never worked for nobles and therefore did not need to know how to make weapons of a superior quality (even among the nobles some were too poor to have the best thing)
