This is a Forge mod.

This mod adds in two new tiers of gear: Steel and Diamond-Enriched Steel. Steel gear is better than Diamond but not as good as Netherite. Diamond-Enriched Steel is better than Netherite.

To obtain Steel, put an Iron Ingot in the Blast Furnace. You'll get one Steel Nugget. The Nuggets function just like Gold and Iron Nuggets. Diamond-Enriched Steel Ingots are crafted from four Diamonds and five Steel Ingots.

Crafting Diamond-Enriched Steel tools requires Steel Rods, which are crafted from eight Steel Ingots and a Blaze Rod, or eight Blaze Rods and a Block of Steel.

The Diamond-Enriched Steel Pickaxe can break Bedrock blocks. Simply left-click the block with the pickaxe in your main hand and voila!

Bedrock has slab, stair, and wall forms with this mod. They have normal crafting recipes and can also be created in the Stonecutter. Don't ask how that works.

The mod includes nine achievements:

Wannabe Industrialist - Obtain your first Steel Nugget.
Cover Me With Steel - Equip a full set of Steel armor.
Into Firebar - Craft your first Steel Rods.
Andrew Carnegie II - Have 64 Blocks of Steel.
Cutting Edge - Craft your first Diamond-Enriched Steel Ingot.
Cover me with - Oh, you know what it's called! - Equip a full set of Diamond-Enriched Steel armor.
Who has that much free time? - Craft 64 Blocks of Diamond-Enriched Steel, then go outside.
Breaking The Mold - Collect Bedrock.
Diagnosed Psychopath - Craft a Diamond-Enriched Steel Hoe, then strongly consider therapy.
